JOSÉ A. CABRANES, Circuit Judge. We consider here whether the application of the licensing requirement of the City of New York (the “City”) to unlicensed street vendors of clothing painted with grafitti violates either these vendors’ rights under the First Amendment or a 1997 permanent injunction entered on consent of the City of New York (the “Bery injunction”) by a district court in Bery v. City of New York, No. 94 Civ. 4253(MGC) (S.D.N.Y. Oct. 30, 1997). Because we hold that New York City’s licensing requirement is a valid, content-neutral restriction on speech and because we do not classify plaintiffs’ merchandise as “paintings” within the meaning of the Bery injunction, we conclude that plaintiffs have not demonstrated a “likelihood of success” on either claim. Accordingly, we vacate the order entered by the United States District Court for the Southern District of New York (Victor Marrero, Judge) granting a preliminary injunction against defendants and remand the cause for further proceedings consistent with this opinion. New York City’s General Vendors Law (“GVL”) regulates the sale of goods and services in public spaces for the purpose of preserving public health, safety, and welfare. New York City Administrative Code § 20-453 — a provision of the GVL — aims to reduce congestion of city streets and sidewalks by requiring any person who “hawks, peddles, sells, leases or offers ... at retail” non-food goods or services to obtain a renewable general vendor’s license from the Department of Consumer Affairs (“DCA”). N.Y.C. Admin. Code §§ 20-452(b); 20-453. Subject to a small number of exceptions, unlicensed vendors may be fined, imprisoned for up to three months, and/or forced to relinquish their merchandise. Id. § 20-472. This administrative scheme was successfully challenged in the 1990s by vendors of paintings, photographs, prints, and sculptures, who asserted, inter alia, that New York City’s licensing requirement unconstitutionally interfered with their First Amendment right to freedom of speech. Considering the matter at the preliminary injunction stage, we held in Bery v. City of New York, 97 F.3d 689 (2d Cir.1996), that (1) vendors of these traditional forms of art “always communicate some idea or concept” and are therefore presumptively “entitled to full First Amendment protection,” id. at 696, and (2) that the City’s licensing requirement violated the First Amendment as applied to plaintiffs because it was not narrowly tailored to the objective of reducing urban congestion, id. at 697-98. After this Court’s decision in Bery and following the Supreme Court’s denial of New York City’s petition for a writ of certiorari, City of New York v. Bery, 520 U.S. 1251, 117 S.Ct. 2408, 138 L.Ed.2d 174 (1997), the City declined to proceed to a trial on the merits to resolve whether its fixed-license regime was narrowly tailored in light of the then-prevailing urban congestion rates and the availability of alternative channels for the sale of expressive merchandise. It also apparently declined to more “narrowly tailor” § 20-453 by adjusting the nature of the licensing requirement itself. Instead, the City consented to the Bery injunction and in doing so stipulated that it would no longer enforce § 20-453 against vendors of “ ‘any paintings, photographs, prints and/or sculpture.’ ” Mastrovincenzo v. City of New York, 313 F.Supp.2d 280, 283 (S.D.N.Y.2004) (quoting the Bery injunction). We now consider whether either this Court’s holding in Bery or the Bery injunction itself prevents the City of New York from enforcing its licensing requirements against plaintiffs, who are sidewalk purveyors of clothing painted with graffiti. In the course of resolving these legal questions, we decline the invitation of plaintiffs (and the District Court) to participate in colloquia on such interesting and lofty matters as the definition of “art,” the Platonic form of a “painting,” and whether a urinal can be a sculpture, see Decl. of Lydia Yee ¶ 17. Rather, we focus narrowly on the ruling of the District Court which preliminarily enjoined the City of New York from enforcing its licensing requirements against plaintiffs on the basis that such requirements violate both the First Amendment and the Bery injunction. We hold, principally, that (1) the sale of clothing painted with graffiti is not necessarily expressive and therefore is not automatically entitled to First Amendment protection; (2) the sale of plaintiffs clothing nonetheless has a predominantly expressive purpose and therefore merits First Amendment protection; (3) New York City’s licensing requirement is a content-neutral restriction on speech that is narrowly tailored to achieve the objective of reducing urban congestion; and (4) the Bery injunction’s reference to “paintings” does not encompass clothing painted with graffiti. Accordingly, we vacate the District Court’s order granting a preliminary injunction against defendants and remand for further proceedings consistent with this opinion. Background I. New York City’s General Vendors Law New York City’s General Vendors Law regulates the sale or offering for sale of non-food goods and services in the public spaces of New York City. The GVL defines a “general vendor” as any person who “hawks, peddles, sells, leases or offers to sell or lease, at retail, [non-food] goods or services ... in a public space.” N.Y.C. Admin. Code § 2(M52(b). At issue in this appeal is the provision of the GVL requiring, subject to certain exceptions described below, that “any individual [wishing] to act as a general vendor” must first obtain a general vendor’s license from the DCA. Id. § 453. A one-year license costs two hundred dollars, id. § 20-454, and a licensee may apply each year for renewal of his license. The DCA must approve a renewal request if the applicant has complied with certain administrative requirements, paid all applicable taxes and fees, and not committed any violation that would support the revocation of his license. Id. §§ 20^456, 457, 459. City regulations specify that no more than 853 general vendor’s licenses may be outstanding at any given time. See id. § 20-459(a) (providing that “the maximum number of licenses permitted to be in effect” shall be “[t]he number of licenses in effect ... on the first day of September, nineteen hundred seventy-nine”); Bery, 97 F.3d at 692 (describing the 1979 passage of Local Law 50, which amended the Administrative Code and fixed the permissible number of outstanding licenses at 853). Because the permissible number of licenses has remained unchanged since 1979, and because current license-holders may annually renew their licenses, there is a substantial backlog of individuals seeking licenses. Due to a handful of statutory exemptions, the actual number of vendors legally selling non-food items at any given time exceeds 853. For instance, honorably discharged members of the United States armed forces who are veterans of any war or who served in the armed forces overseas are awarded licenses to vend publicly without being constrained by the license limit. See N.Y. Gen. Bus. Law § 32 (“Every honorably discharged member of the armed forces of the United States, who is a resident of this state and a veteran of any war, or who shall have served in the armed forces of the United States overseas ... shall [acquire] the right to hawk, peddle, vend and sell goods, wares or merchandise or solicit trade upon the streets [by obtaining a special veteran’s license at no cost] ----”); Bery, 97 F.3d at 692; Mastrovincenzo, 313 F.Supp.2d at 282 n. 1. Likewise, individuals selling “only newspapers, periodicals, books, pamphlets or other similar written matter” are exempted from the licensing requirement. See N.Y.C. Admin. Code § 20-453; Bery, 97 F.3d at 692 (describing the 1982 passage of Local Law 33, which amended the Administrative Code to exempt vendors of written materials from the GVL’s licensing requirement). New York City has also agreed, under the terms of the Bery injunction, not to enforce its licensing requirement against individuals selling “paintings, photographs, prints and/or sculpture.” See Background, II, post. All general vendors, including those who are exempt from New York City’s licensing requirement, must comply with the GVL’s other restrictions concerning the size, location, and placement of vendors’ displays. See N.Y.C. Admin. Code § 20-452(b). These regulations specify, inter alia, that vendors may not (1) operate on sidewalks less than twelve feet wide, (2) occupy more than eight linear feet parallel to a curb, (3) display their wares within twenty feet of an entrance to any “place of public assembly,” (4) occupy a bus or taxi stand, or (5) obstruct subway access. See id. § 2CM65 (specifying detailed restrictions on the time, place and manner in which licensed vendors may peddle goods and services); see also Bery, 97 F.3d at 692 (summarizing the provisions of § 20-465); Mastrovincenzo, 313 F.Supp.2d at 282 n. 2 (same). A non-exempt vendor — i.e., a non-veteran who sells any non-food goods other than written materials or artwork of the kind specified in the Bery injunction — who attempts to sell his wares in public spaces without a license is subject to civil and criminal penalties. He may be charged with a misdemeanor punishable by a fine of between $250 and $1,000, and/or imprisonment for up to three months, and his wares may be seized and forfeited. See N.Y.C. Admin. Code §§ 20-468, 469, 472. It is not disputed that the New York City Council (“City Council”) — -which is broadly authorized to enact regulations designed to promote and protect the welfare of New York City residents, see Charter of New York City § 21 (outlining the broad legislative authority of the City Council); see also Fisher Scientific Co. v. City of New York, 812 F.Supp. 22, 25 (S.D.N.Y. 1993) (“The City Council and its committees possess and exercise all of the legislative power of the City of New York.”)— enacted the licensing requirement for general vendors with a view toward promoting the public interest. According to the City Council, the public health, safety and welfare are threatened by the unfettered use of city streets for commercial activity by unlicensed, and therefore illegal, general vendors. Such illicit operations have a pernicious effect on both the tax base and economic viability of the City. Unlicensed general vendors do not pay taxes, often sell stolen, defective or counterfeit merchandise .... The practice of selling their wares ... impedes the flow of pedestrian traffic, caus[es] the overflow of traffic, and, at worst, it creates the potential for tragedy. Mastrovincenzo, 313 F.Supp.2d at 283 (quoting New York City Local Law 40/1988 § 1). II. The Bery Case and the Bery Injunction On June 9, 1994, a group of artists (the “Bery plaintiffs”) brought suit against the City of New York for its refusal to exempt them from the licensing requirement of the GVL. The Bery plaintiffs were characterized first by the district court as “artists who sell their original paintings on public sidewalks and an artists’ advocacy organization,” Bery v. City of New York, 906 F.Supp. 163, 165 (S.D.N.Y.1995), and later by our Court as “individual artists engaged in painting, photography and sculpture and an artists’ advocacy organization,” Bei*y, 97 F.3d at 691; see Discussion, IV, post. The Bery plaintiffs sought a preliminary injunction “prohibiting the enforcement against them of the ... General Vendors Law ... on the grounds that the application of the ordinance to their activities violate[d] their rights to freedom of expression and equal protection of the laws under the First and Fourteenth Amendments to the Constitution.” Bery, 906 F.Supp. at 165. The district court denied their motion for a preliminary injunction, id. at 170, and a panel of our Court reversed that judgment, Bery, 97 F.3d at 699. The Bery Court noted that “[vjisual art is as wide ranging in its depiction of ideas, concepts and emotions as any book, treatise, pamphlet or other writing,” and concluded that the Bery plaintiffs’ artwork was “expressive merchandise” that did not lose its status as protected speech merely because plaintiffs sought compensation for their art. Id. at 695-96. Despite a suggestion that the Bery plaintiffs’ artwork was, by virtue of its status as visual art, automatically “entitled to full First Amendment protection,” id. at 695, in fact, the Court’s analysis proceeded in two distinct stages: first, the Bery plaintiffs’ artwork was found to be sufficiently expressive to trigger First Amendment review of New York City’s licensing requirement, id. at 696, and second, “the license requirement as it relate[d] to [the Bery plaintiffs] [was held to be] too sweeping to pass constitutional muster,” id. at 697. In reaching the threshold conclusion — that the Bery plaintiffs’ artwork was sufficiently expressive to trigger First Amendment review — the Bery Court explained that [w]hile [the crafts of the jeweler, the potter and the silversmith] may at times have expressive content, paintings, photographs, prints and sculptures, such as those [the Bery plaintiffs] seek to display and sell in public areas of the City, ahoays communicate some idea or concept to those who view it, and as such are entitled to full First Amendment protection. Id. at 696 (emphasis added). Recognizing the inherent line-drawing problems associated with distinguishing among artwork with presumptively expressive content (such as that sold by the Bery plaintiffs), merchandise with potentially expressive content (such as “the crafts of the jeweler, the potter and the silversmith,” id.), and merchandise with no expressive content, the Bery Court offered the following faint consolation to other judges who would be confronted with such matters in the future: Courts must determine what constitutes expression within the ambit of the First Amendment and what does not. This surely will prove difficult at times, but that difficulty does not warrant placing all visual expression in limbo outside the reach of the First Amendment’s protective arm. Courts have struggled with such issues in the past; that is not to say that decisions are impossible. Id. While the Bery Court foreclosed the categorical placement of “all visual expression” outside the reach of the First Amendment, it left open the “difficult” question of when the sale of assertedly artistic items constitutes protected speech under the First Amendment. At a second stage of analysis, the Bery Court applied the First Amendment doctrine that governs content-neutral “time, place, and manner” restrictions on protected speech and held that the Bery plaintiffs could likely demonstrate that New York City’s licensing requirement was not “‘narrowly tailored to serve a significant governmental interest’ ” and did not “ ‘leave[ ] open ample alternative channels for communication.’ ” Id. at 697 (quoting Ward v. Rock Against Racism, 491 U.S. 781, 791, 109 S.Ct. 2746, 105 L.Ed.2d 661 (1989)). The Bery Court reasoned that New York City’s licensing regime, by denying licenses to emerging artists such as the Bery plaintiffs, effectively “bar[red] an entire category of expression,” id. at 697, and left plaintiffs with a lack of ample alternative venues for displaying their artwork, id. at 698. Instead of contesting this preliminary determination in a trial on the merits or adjusting the substance of its licensing requirement, New York City consented to a permanent injunction (the “Bery injunction”) prohibiting it from “enforcing [N.Y.C.] Admin. Code § 20-453 against any person who hawks, peddles, sells, leases or offers to sell or lease, at retail, any paintings, photographs, prints and/or sculpture, either exclusively or in conjunction with newspapers, periodicals, books, pamphlets or other similar written matter, in a public space[.]” Permanent Injunction on Consent dated Oct. 21, 1997, Bery v. City of New York, No. 94 Civ. 4253(MGC) (S.D.N.Y. Oct. 30, 1997); see also Mastrovincenzo, 313 F.Supp.2d at 283. III. Plaintiffs and Their Merchandise Plaintiffs Christopher Mastrovincenzo and Kevin Santos are “trained freelance artists,” Mastrovincenzo, 313 F.Supp.2d at 283, with substantial artistic backgrounds. In the words of the District Court, plaintiffs “offer for sale in public places without a license articles of clothing that they individually decorate with text and images in what they label a graffiti style.” Id. at 282. Plaintiffs describe their “graffiti style”— alternatively dubbed the “hip-hop” style— as “highly stylized typography, iconography, and pictorial representation ... [using] varying combinations of oil paints, spray paints, markers, and permanent paint pens” that they apply “primarily on hats and other items of clothing.” Appel-lees’ Br. at 3. Plaintiffs do not characterize their merchandise primarily as “clothing,” but rather, as “artwork” on nontraditional canvases. Id. at 4. According to plaintiffs, “[e]ach piece is an individual work of art customized on the spot according to the client’s request, and includes such things as names, characters, and pictures on the hats.” Compl. ¶ 27. Plaintiffs further assert that they “charge different fees for their artwork based solely on the complexity and difficulty of the art they produce [and] do not charge anything for [the] items of clothing [themselves].” Id. ¶ 38. In 2002, plaintiffs each applied for a vendor’s license from the DCA, but their applications were denied. Plaintiffs nevertheless deliberately proceeded to establish sidewalk displays of their items, offering them for sale in public. On July 20, 2003, Mastrovincenzo was arrested for selling merchandise without a license and his goods were seized and later sold at auction. While the charges stemming from Mastrovincenzo’s first arrest were ultimately dropped, he was arrested for the same offense on September 24, 2003 and allegedly incarcerated for eight hours. Santos was not arrested, but he was repeatedly instructed by New York City police officers to shut down his display. Thereafter, Santos arranged for his merchandise to be sold on commission through licensed vendors “rather than risk arrest.” Mastrovincenzo, 313 F.Supp.2d at 284. During the summer and fall of 2003, through correspondence and discussion initiated by their respective attorneys, plaintiffs sought the permission of the DCA to sell their merchandise on New York City sidewalks without a license. Those negotiations were unsuccessful, and plaintiffs thereafter filed this suit, seeking to enjoin the City from enforcing § 20-453 against them. IV. Plaintiffs’ Complaint and the District Court’s Decision and Order Plaintiffs filed suit on January 20, 2004, alleging that defendants’ refusal to permit them to sell their merchandise on public sidewalks violates (1) their rights under the First and Fourteenth Amendments, see id. ¶¶ 51-54; (2) the Bery Injunction, see Compl. ¶¶ 48-50; and (3) sections 8 and 11 of Article 1 of the New York State Constitution, see id. ¶¶ 55-56. Concurrent with the filing of their complaint, plaintiffs filed a motion for preliminary injunction. The District Court granted plaintiffs’ motion for preliminary injunction — barring defendants from enforcing § 20-453 against plaintiffs — in a Decision and Order dated April 7, 2004. The District Court began by observing that “the First Amendment protects the sale of expressive merchandise,” Mastrovincenzo, 313 F.Supp.2d at 285, and then set about determining whether plaintiffs’ items qualified as such. The District Court then postulated that “[civilization has traveled too far down the road in the evolution of art as embracing the whole spectrum of human imagination for the law to countenance a classification of an artist’s design as art only when imparted in conventional shapes and forms sufficiently familiar or acceptable to a government licensor.” Id. at 289. “Just as expression is not limited to the written and spoken word,” the District Court elaborated, “neither is nonverbal expression restricted to paintings, photographs, prints and sculptures.” Id. With regard to plaintiffs’ merchandise, the District Court concluded that [t]he items in the present case are individually produced and hand-painted. They are not merely aesthetically pleasing designs used as a means of selling hats and jackets but rather they are expressive works of art .... Most of the items shown to the Court contain text that, on its own or through its style, is as expressive as any sidewalk calligrapher or Chinese-character painter, apparently neither of whom needs a license from the DCA to produce and sell their wares in the City’s streets. Id. at 291. Having found that plaintiffs’ items qualify as “expressive works of art,” the District Court nevertheless conceded that “almost every object can conceivably be interpreted as having some expressiveness,” id. at 292, and that “not everything labeled or hawked as art [should be considered expressive art],” id. at 287. The District Court explained that, in the course of deciding whether the sale of plaintiffs’ merchandise falls “within of the realm of the First Amendment,” it took into account “myriad factors,” id. at 292. Among other criteria, the Court considers: [1] the individualized creation of the item by the particular artist, [2] the artist’s primary motivation for producing and selling the item, [3] the vendor’s bona tides as an artist, [4] whether the vendor is personally attempting to convey his or her own message, and [5] more generally whether the item appears to contain any elements of expression or communication that objectively could be so understood. No one factor can control the outcome — as is the case in connection with many other judicial decisions concerning borderline issues, the criteria fit together to form a matrix. Certainly an item may be sufficiently expressive to fall within the realm of the First Amendment regardless of, for example, the educational background of its creator. At bottom, the purpose of the inquiry is to determine the degree of the item’s expressiveness, which may best be accomplished by examining it in the light of objective considerations. Id. Fearful of imposing “a chilling effect on genuine artists whose true calling is art and not commerce,” the District Court held that New York City’s application of its licensing regime to plaintiffs violated their First Amendment rights to free speech. Id. The District Court added that even if plaintiffs had not successfully challenged New York City’s licensing requirement on First Amendment grounds, they could alternatively have prevailed on their Bery injunction claim. Citing what it described as the “broadly-written” language of the Bery injunction — that defendants City of New York and the DCA may not enforce § 20-453 against “any person who ... sells ... any paintings” — and the fact that the Bery injunction does not define the term “paintings,” the District Court reasoned that “[a] painting does not lose its definition as painting, or generally as art, when it appears on something other than a framed canvas.” Id. at 293. Accordingly, the District Court concluded that “[a]s written, the Bery Injunction provides protection to [plaintiffs’ works even if no ... dispute arose as to whether the First Amendment does.” Id. On April 21, 2004, defendants timely appealed from the District Court’s order granting plaintiffs’ motion for prehminary injunction. See 28 U.S.C. § 1292(a)(1) (providing appellate jurisdiction to review orders granting preliminary injunctions). Discussion On appeal, defendants argue that the District Court erred by (1) ordering what was a “mandatory” (rather than “prohibitory”) injunction without having conducted the proper “clear or substantial” likelihood-of-success analysis that is required for mandatory injunctions; (2) concluding that plaintiffs were likely to succeed on their First Amendment claim; and (3) determining that plaintiffs’ wares are “paintings” within the meaning of the Bery injunction, which separately limits New York City’s enforcement of § 20-453. We review a district court’s decision to grant a preliminary injunction for abuse of discretion. The District Court abuses its discretion “when (1) its decision rests on an error of law (such as application of the wrong legal principle) or a clearly erroneous factual finding, or (2) its decision — though not necessarily the product of a legal error or a clearly erroneous factual finding — cannot be located within the range of permissible decisions.” Zervos v. Verizon N.Y., Inc., 252 F.3d 163,169 (2d Cir.2001) (footnotes omitted). I. Whether the Injunction Is “Mandatory” or “Prohibitory” Defendants argue that the preliminary injunction requested in this case was mandatory, rather than prohibitory, and insist that the District Court should therefore have applied a more stringent test when evaluating whether to enter a preliminary injunction. See Appellants’ Br. at 11-15. A district court may enter a prohibitory preliminary injunction staying “government action taken in the public interest pursuant to a statutory or regulatory scheme” only when the moving party has demonstrated that (1) absent injunc-tive relief, he will suffer “irreparable injury,” and (2) there is “a likelihood that he will succeed on the merits of his claim.” Plaza Health Labs., Inc. v. Perales, 878 F.2d 577, 580 (2d Cir.1989). Alternatively, a district court may enter a mandatory preliminary injunction against the government only if it determines that, in addition to demonstrating irreparable harm, the moving party has shown a “clear” or “substantial” likelihood of success on the merits. No Spray Coalition, Inc. v. City of New York, 252 F.3d 148, 150 (2d Cir.2001) (quoting Rodriguez v. DeBuono, 175 F.3d 227, 233 (2d Cir.1999)). The District Court correctly treated plaintiffs’ requested preliminary injunction as prohibitory and stated the proper test for determining whether such an injunction was warranted. The Court may grant a preliminary injunction to stay government action taken in the public interest pursuant to a statutory scheme when the moving party establishes [1] that it will suffer irreparable harm absent the injunction and [2] that it is likely to succeed on the merits of its claim. [Because] [i]t is well settled that the loss of First Amendment freedoms, for even minimal periods of time, unquestionably constitutes irreparable injury ... [the relevant issue in this case is] [plaintiffs’ likelihood of success on the merits of their claims. Mastrovincenzo, 313 F.Supp.2d at 284-85 (internal quotation marks and citations omitted). Defendants do not challenge the District Court’s statement of the legal standard for granting prohibitory injunctions; rather, they insist that the requested preliminary injunction in this case was mandatory, rather than prohibitory. See Appellants’ Br. at 13. In particular, defendants draw our attention to language in the Complaint (“[u]nless restrained by [the District] Court, [defendants will continue to enforce the Ordinance against [p]laintiffs,” Appellant’s Br. at 13 (quoting Compl. ¶ 47)) to argue that the licensing requirement is so regularly and consistently enforced that enjoining them from continuing to enforce it would, in effect, affirmatively force the City to change its conduct, thereby warranting the heightened mandatory injunction analysis. In distinguishing between prohibitory and mandatory injunctions, we have noted that “[t]he typical preliminary injunction is prohibitory and generally seeks only to maintain the status quo pending a trial on the merits. A mandatory injunction, in contrast, is said to alter the status quo by commanding some positive act ... [and] thus alters the traditional formula by requiring that the movant demonstrate a greater likelihood of success.” Tom Do-herty Assocs. v. Soban Entm’t, Inc., 60 F.3d 27, 34 (2d Cir.1995) (emphasis added). Accordingly, we first look to the terms of the injunction issued by the District Court, which reads: ORDERED that defendants ... are enjoined from enforcing New York City Administrative Code § 20-453 against Plaintiffs pending the final resolution of this litigation in this Court[.] Mastrovincenzo, 313 F.Supp.2d at 294. On its face, the injunction clearly prohibits, rather than compels, government action by enjoining the future enforcement of § 20-453 against plaintiffs. We are aware that “the distinction between mandatory and prohibitory injunctions is not without ambiguities or critics” and often leads to “distinctions that are moi*e semantie[] than substantive.” Tom Doherty Assocs., 60 F.3d at 34 (internal quotation marks omitted) (alteration in original). Because “in borderline cases in-junctive provisions containing essentially the same command can be phrased either in mandatory or prohibitory terms,” Int’l Union, United Mine Workers of Am. v. Bagwell, 512 U.S. 821, 835, 114 S.Ct. 2552, 129 L.Ed.2d 642 (1994), we have, on exceptional occasions, looked beyond the terms of the injunction itself, see, e.g., SEC v. Unifund SAL, 910 F.2d 1028, 1039-40 (2d Cir.1990) (imposing a “substantial showing of likelihood of success” requirement despite recognizing that “the order is prohibitory in form”). Here, however, we need not look beyond the terms of the injunction because it clearly does not command the City of New York or the DCA to perform any specific tasks. If, as defendants suggest, the action prohibited in the instant case is so regular and consistent that the injunction must be designated as de facto mandatory, then the same would surely have been true in Bery. Notably, however, the Bery Court did not apply the heightened standard for mandatory injunctions to the injunction sought there. See Bery, 97 F.3d at 694. A heightened “substantial likelihood” standard may also be required when the requested injunction (1) would provide the plaintiff with “all the relief that is sought” and (2) could not be undone by a judgment favorable to defendants on the merits at trial. Tom Doherty Assocs., 60 F.3d at 34-35; see, e.g., Beal v. Stem, 184 F.3d 117, 122-23 (2d Cir.1999) (applying heightened standard where preliminary injunction would have permitted plaintiffs to hold large rally in public place, thereby rendering the dispute moot after entry of injunction). In this instant case, however, defendants have not shown that the injunction effects a particularly drastic or irreversible change in the status quo. Instead, the ultimate question of whether New York City may impose its licensing requirements on vendors of clothing painted with graffiti remains ripe for resolution on the merits, and the injunction did not irreversibly affect the rights of the parties. In sum, we find no support in our case law for the proposition that an injunction that is prohibitory in form and that promises no severe or irreversible changes to the status quo may be recast as, or transformed into, a mandatory injunction simply by a reference to the predictability and certainty of the action enjoined. We therefore hold that the District Court did not err in evaluating plaintiffs’ motion for preliminary injunction under the test for prohibitory injunctions, and we review the District Court’s order granting that motion accordingly. II. The First Amendment Basis for the Injunction At the outset, we underscore that we do not purport to resolve whether plaintiffs’ wares fit within, or can be reconciled with, broader societal definitions of “art,” a famously malleable concept the contours of which are best defined not by courts, but in the proverbial “eye of the beholder.” Rather, in reviewing the District Court’s conclusion that plaintiffs would likely prevail on the merits of their claim that § 20-453 violates their First Amendment rights to free speech, we address (1) whether the District Court correctly concluded that the sale of plaintiffs’ items was predominantly expressive and on that basis properly subjected New York City’s licensing requirement to First Amendment scrutiny, and (2) whether the District Court properly determined that New York City’s licensing fails an intermediate standard of scrutiny and therefore violates plaintiffs’ First Amendment rights. We are aware, of course, that objects themselves do not actually communicate— people do. That is, people may, by creating or selling artistic objects, engage in protected speech. See, e.g., Bery, 97 F.3d at 695. Accordingly, to resolve whether the First Amendment protects the sale of graffiti clothing, we must ultimately determine whether the disseminators of that clothing are genuinely and primarily engaged in artistic self-expression or whether the sale of such goods is instead a chiefly commercial exercise. Because the most reliable means of resolving this difficult question is to examine objective features of the merchandise itself, however, we begin by analyzing whether plaintiffs’ items, on their face, appear to serve predominantly expressive purposes. After evaluating the nature of plaintiffs’ merchandise, we also take into account other factors such as plaintiffs’ stated motivation for producing and selling their graffiti clothing. We stress that our threshold analysis of the objective characteristics of plaintiffs’ wares should be understood not as a separate “expressive merchandise” test, but rather, as the first step of a larger inquiry into whether plaintiffs are engaged in protected speech — an inquiry which may also be informed by other, more subjective considerations. (A) Whether the sale of plaintiffs’ graffiti-painted clothing is protected speech For purposes of First Amendment coverage, “the Constitution looks beyond written or spoken words as mediums of expression,” Hurley v. Irish-Am. Gay, Lesbian and Bisexual Group of Boston, 515 U.S. 557, 569, 115 S.Ct. 2338, 132 L.Ed.2d 487 (1995), extending its protection to include, inter alia, “pictures, films, paintings, drawings, and engravings,” Kap-lan v. California, 413 U.S. 115, 119-20, 93 S.Ct. 2680, 37 L.Ed.2d 492 (1973). In the words of the Supreme Court, if the First Amendment protected only expressive conduct “conveying a ‘particularized message,’ [it] would never reach the unquestionably shielded painting of Jackson Pollack, music of Arnold Schoenberg, or Jabberwocky verse of Lewis Carroll.” Hurley, 515 U.S. at 569, 115 S.Ct. 2338 (internal citation omitted). Of equal importance to plaintiffs, “the degree of First Amendment protection” to which speech is entitled “is not diminished merely because the ... speech is sold rather than given away.” City of Lakewood v. Plain Dealer Publ’g Co., 486 U.S. 750, 756 n. 5, 108 S.Ct. 2138, 100 L.Ed.2d 771 (1988); see also Ayres v. City of Chicago, 125 F.3d 1010, 1014 (7th Cir. 1997) (noting that items “do not lose their [First Amendment] protection by being-sold rather than given away.”). As noted, we held in Bery that “paintings, photographs, prints and sculptures ... always communicate some idea or concept to those who view it, and as such are entitled to full First Amendment protection.” Bery, 97 F.3d at 696. Beyond this statement, however, there is a notable dearth of precedent — both within our Circuit and beyond — offering guidance as to when a product should be said to serve predominantly expressive purposes, and in turn, when its sale or dissemination is protected under the First Amendment. As the District Court acknowledged, “the mere possibility that an item could be labeled ‘art’ does not necessarily eon[fer] First Amendment protection on the item.” Mastrovincenzo, 313 F.Supp.2d at 289. The observation that any object with a size, shape and density has the potential to be art (notwithstanding, we are instructed, the “myopic” perspective of those Philistines who recognize art only in its “conventional shapes and forms,” see Bery, 97 F.3d at 695; Mastrovincenzo, 313 F.Supp.2d at 289), is a truism, and, in legal terms, not entirely helpful. To say that the First Amendment protects the sale or dissemination of all objects ranging from “totem poles,” see Mastrovincenzo, 313 F.Supp.2d at 289, to television sets does not take us far in trying to articulate or understand a jurisprudence of ordered liberty; indeed, it would entirely drain the First Amendment of meaning. The Bery Court anticipated the line-drawing problem that it bequeathed to successor panels when it airily noted that while future courts would surely find it “difficult at times” to apply the principles expounded in Bery, they could nonetheless be counted upon to formulate more precise and workable doctrine. Bery, 97 F.3d at 696. Whatever may be said of Bery’s analytic framework, see, e.g., White v. City of Sparks, 341 F.Supp.2d 1129, 1139 (D.Nev. 2004) (“Applying such a blanket presumption of protected status [as Bery ] would not only be unnecessary ... but would also be out of step with ... the First Amendment’s fundamental purpose — to protect expression.”), it remains the law of the Circuit until and unless it is effectively superseded by decisions of the Supreme Court or formally revisited by the Court sitting en banc, see, e.g., United States v. Santiago, 268 F.3d 151, 154 (2d Cir.2001) (noting that we are bound by a prior panel’s holding “unless it has been called into question by an intervening Supreme Court decision or by one of this Court sitting in banc.”). We therefore turn to the “difficult” assignment left for us by the Bery Court. At the outset, we must determine whether the sale of plaintiffs’ goods is presumptively entitled to First Amendment protection, or more precisely, whether the expressive capacity of plaintiffs’ goods is such that we automatically apply First Amendment scrutiny to regulations that restrict their sale or dissemination. In Bery, we made clear that only certain items — “paintings, photographs, prints and sculptures” — automatically trigger First Amendment review because the sale or dissemination of these items “always corn-municate[s] some idea or concept” to viewers. Bery, 97 F.3d at 696. Where, as in the instant case, items do not fall within one of these four categories, their sale must be classified as potentially expressive. The Bery Court placed in this second category “the crafts of the jeweler, the potter, and the silversmith,” whose works “at times have expressive content.” Id. As the District Court accurately summarized, the Bery Court was “unwilling to provide blanket protection for all jewelry, pottery and metalwork because such items do not always communicate an idea or concept to the viewer.” Mastrovincenzo, 313 F.Supp.2d at 289 (emphasis added). Instead, as the District Court observed, “[f]or these and other items, as distinct from paintings, photographs, prints and sculptures, courts must conduct case-by-case evaluations to determine whether the work at issue is sufficiently expressive.” Id. (emphasis added). Accordingly, in the nature of things, some such items ultimately may be characterized as “expressive” while others may be deemed “mere commercial goods” — that is, goods whose characteristics suggest that their vendors are not engaged in protected speech. See id. at 285 (distinguishing between “expressive merchandise” and “[m]ere commercial goods”). The District Court’s examination of plaintiffs’ wares more or less followed this analytical framework. Taken out of context, certain statements by the District Court could be read to suggest that the category of presumptively expressive items extends beyond paintings, photographs, prints and sculptures, see, e.g., id. at 286 (“The Bery court spoke in terms of paintings, photographs, prints and sculptures, but clearly held a much broader conception of what qualifies as artistic expression.”). But as the District Court’s subsequent analysis confirms, its reference to Bery’s “broader” conception of artistic expression is merely an acknowledgment that the sale of certain objects not encompassed within the four categories of presumptively expressive items may nonetheless be deemed expressive following a case-by-case evaluation of “myriad factors.” Id. at 292. In reaching its conclusion that plaintiffs’ graffiti clothing is “at least as likely to be understood by some viewers as a Jackson Pollack painting” and just “as expressive as [the works of] any sidewalk calligrapher,” id. at 291, the District Court explicitly took into consideration five factors: (1) whether the items were “individually] creat[ed] ... by the particular artist”; (2) “the artist’s primary motivation for producing ... the item”; (3) “the vendor’s bona fides as an artist;” (4) “whether the vendor is personally attempting to convey his or her own message”; and (5) “whether the item appears to contain any elements of expression or communication that objectively could be so understood,” id. at 292. The District Court explained that “[n]o one factor ... controlled] the outcome,” stressing instead that “the criteria fit together to form a matrix.” Id. We commend the District Court for seeking, in the difficult circumstances created by our open-ended ruling in Bery, to formulate organizing principles for determining when the sale of goods that are not presumptively expressive-i.e., items other than paintings, photographs, prints, and sculptures — should nonetheless be protected under the First Amendment, but we take this opportunity to modify its proposed multi-pronged test to render it consistent with accepted First Amendment principles. The District Court correctly surmised that while “myriad factors will guide any inquiry into whether a vendor’s wares are sufficiently expressive to merit First Amendment protection,” this inquiry is “best ... accomplished by examining [the items] in the light of objective considerations.” Id. at 292. The District Court incorporated these “objective considerations” into its final and most important factor — namely, whether an item “appears to contain any elements of expression or communication that objectively could be so understood.” Id. While, for the reasons stated below, we cannot embrace the precise wording of the District Court’s final factor — which inquires whether “any elements of expression or communication” are present — we nonetheless agree with the District Court that the most reliable means of determining whether a vendor is primarily engaged in an act of self-expression is not to consult the vendor himself (who will, in most instances, have a strong incentive to emphasize his artistic motivations), but rather to examine the expressive content of the materials being sold. Were courts to consider (as the District Court suggests) only whether an item could be objectively understood to have any expressive or communicative elements, the protections of the First Amendment might then be expanded to encompass the sale of a broad array of merchandise with only incidental artistic elements, including, for example, playing cards with artistic designs on the back, see People v. Saul, 3 Misc.3d 260, 776 N.Y.S.2d 189, 192-93 (2004) (holding that playing cards bearing photographs of Iraqi military or political figures were not sufficiently expressive to receive First Amendment protection and thereby to exempt sellers from § 20-453), T-shirts emblazoned with the stars and stripes, see Mas-trovincenzo, 313 F.Supp.2d at 288 (denying that such apparel would merit First Amendment protection), or for that matter, any object bearing a floral pattern or painted design on its exterior, such as a bicycle, an item of stereo equipment, a garbage can, or a raincoat. Fortunately, we need not engage in such interesting and creative, but ultimately absurd, intellectual exercises. We live in the real world, with law enforcement decisions being made by policemen on the beat as well as others who must be able to understand the law to be applied without recourse to principles of aesthetics. We therefore apply a test that is as straightforward as we can devise under the circumstances presented. Once a court has determined that an item possesses expressive elements, it should then consider whether that item also has a common non-expressive purpose or utility. Because merchandise that clearly has a alternative, non-expressive purpose — such as the recreational, apparel, and transportation goods mentioned above — is more likely to possess only marginally expressive content or to have been minimally embellished for the purpose of avoiding regulation, courts should exercise greater skepticism in designating such items as “expressive merchandise.” The fact that an object serves some utilitarian purpose does not, however, automatically render it non-expressive; rather, upon a finding that the item in question possesses some common non-expressive purpose, a court should then determine whether that non-expressive purpose is dominant or not. Where an object’s dominant purpose is expressive, the vendor of such an object has a stronger claim to protection under the First Amendment; conversely, where an object has a dominant non-expressive purpose, it will be classified as a “mere commercial good[ ],” the sale of which likely falls outside the scope of the First Amendment. Id. at 285. Although we have not, until now, tried to articulate the importance of identifying a dominant expressive purpose for First Amendment inquiries of this kind, this principle is strongly implied by our decision in Bery. There, we distinguished a small set of presumptively expressive items — such as paintings, photographs, prints and sculpture — from other, potentially expressive items that we characterized as “crafts” — such as those of the jeweler, the potter, and the silversmith. Bery, 97 F.3d at 696. Plainly, the distinction we drew in Bery rested upon a perceived difference of dominant purpose: whereas those items in the former group always have dominant expressive purposes, those in the latter group often have dominant non-expressive purposes. A cufflink fastens the cuff and keeps the shirtsleeve from crowding the wrist; a pot serves as a tidy and dry depository for food and other objects, and cutlery (or, for that matter, a silver plate), even if wrought with substantial skill and artistry, most often serves a predominantly non-expressive purpose. In the instant case, the District Court signaled its appreciation for this distinction when it noted that conduct “very often has a dominant non-expressive purpose,” but that “genuine art” does not. Mastrovincenzo, 313 F.Supp.2d at 287. Regarding the question of when an item’s expressive purpose should be considered “dominant,” we have confidence that district courts will prove capable of making such determinations in much the same way that we distinguished between categories of goods in Bery, and in the way that courts have dealt on a case-by-case basis with difficult line-drawing problems in other First Amendment contexts. For those items with common non-expressive uses that are also sold to customers (rather than given away), courts may gauge the relative importance of the items’ expressive character by comparing the prices charged for the decorated goods with the prices charged for similar non-decorated goods. If a vendor charges a substantial premium for the decorated work and/or does not sell the item without decoration, such facts would bolster his claim that the items have a dominant expressive purpose. Conversely, objects adorned with only minor artistic adjustments — such as bicycles that have been marked by a splotch of red paint — before being sold at rates indistinguishable from ordinary bicycles, might well be classified as “mere commercial goods” because their expressive character is not dominant. Applying the above framework to plaintiffs’ merchandise, we find that plaintiffs’ items (1) could be objectively understood to have expressive or communicative elements but (2) also have several clear non-expressive purposes — namely, shielding the eyes and head from the sun, calming and controlling unruly hair. Accordingly, we proceed to consider whether the expressive elements of plaintiffs’ items may fairly be characterized as dominant. Based upon our review of the record, we hold that the plaintiffs’ items have a predominantly expressive purpose. Plaintiffs’ works “contain text ... depict public figures such as the President or contain logos or designs.” Id. at 284. Mastrovincenzo’s work includes “decorated baseball caps with such words as ‘Boston,’ ‘Unique,’ or ‘Uptown’ (in a stars and stripes motif) painted across the front.” Id. at 290. Santos’s work includes caps “with words and designs such as ‘Bronx’ painted in army camouflage colors and accompanied by a partial subway map of the Bronx; ... ’1984’ in green and purple on a background of vertical black rectangles and black cloud-shaped splotches; and several representational scenes.” Id. Moreover, we note that “[njeither [plaintiff] sells blank, unadorned hats. Each charges between $10 and $100 per hat ... based on the complexity of the design and effort involved in completing it.” Id. at 284. While plaintiffs’ items clearly have non-expressive uses, we conclude that these non-expressive uses are secondary to the items’ expressive or communicative characteristics. Our conclusion that plaintiffs’ wares appear, on their face, to serve a predominantly expressive purpose provides a strong indication that plaintiffs are engaged in protected speech, yet it does not end our inquiry. Rather, we also take into account other factors that shed light on how and why an object is being sold or disseminated. While we decline here to set forth an exhaustive list of all possible factors that courts may wish to consider in future circumstances, which may differ in unpredictable ways from the case at bar, we consider: (1) whether an artist’s stated “motivation for producing and selling [an] item” is his desire to communicate ideas, id. at 292, and (2) whether a vendor (if different from the artist) purports, through the sale of goods, to be engaging in an act of self-expression rather than a mere commercial transaction. Moreover, we specifically reject the District Court’s third factor, which takes into account a “vendor’s bona fides as an artist” in determining whether an item is expressive merchandise, and in turn, whether its vendors are engaged in protected speech. Because we find no basis in the law of the First Amendment for inquiring into the expressiveness of an item by reference to its creator’s curriculum vitae, and because we recognize the potentially undesirable effects of such an inquiry, we expressly reject that element of the District Court’s “myriad factors” analysis. We note that plaintiffs’ own testimony concerning their motivation for producing and selling their graffiti items confirms our prior conclusion that they are primarily engaged in acts of self-expression. For example, Santos stated that his “work is an expression of the particular idea represented on the work, as well as [his] own upbringing and style as an artist, identifiable as [his] own by the style and techniques used as well as by his signature.” Decl. of Kevin Santos ¶ 14 (emphasis added). Santos added that his “artwork is both an important means of personal expression and [his] primary source of income.” Id. ¶ 21. Along similar lines, Mas-trovincenzo stated that his “overarching ambition is to convey a message in a language that people can understand and relate to, but that has aesthetic qualities that seem to ‘flow.’” Decl. of Christopher Mastrovincenzo ¶ 8 (emphasis added). He added that “he began to display and sell [his] hand-painted hats ... as a means of artistic expression” even though they also represent his “primary form of income.” Id. ¶ 11. Accordingly, we hold that plaintiffs’ graffiti goods serve a predominantly expressive purpose, and their sale is consequently protected under the First Amendment. Yet the conclusion that plaintiffs’ items are protected is not tantamount to a finding that New York City’s licensing requirement, N.Y.C. Admin. Code § 20-453, violates plaintiffs’ First Amendment rights. Rather, to reach the latter question, we must consider (1) whether § 20-453 is a content-based or content-neutral regulation, and (2) whether § 20^453, as applied to plaintiffs, can withstand the corresponding First Amendment scrutiny. (B) Whether New York City’s Licensing Requirement Violates Plaintiffs’ First Amendment Rights At the heart of our First Amendment jurisprudence lies the concern “that if the government were able ‘to impose content-based burdens on speech,’ it could ‘effectively drive certain ideas or viewpoints from the marketplace.’” Hobbs v. County of Westchester, 397 F.3d 133, 148 (2d Cir.2005) (quoting Simon & Schuster, Inc. v. Members of N.Y. State Crime Victims Bd., 502 U.S. 105, 116, 112 S.Ct. 501, 116 L.Ed.2d 476 (1991)). As a safeguard against government censorship, we consider “regulations of speech based on its content [to be] presumptively invalid,” id. at 149 (internal quotation marks omitted), upholding such regulations only if they withstand strict scrutiny. On the other hand, we apply “intermediate scrutiny” to regulations of expressive activity that are not based on content. Content-neutral regulations may limit the time, place, or manner of expression — whether oral, written, or symbolized by conduct — even in a public forum, so long as the restrictions are reasonable, are narrowly tailored to serve a significant governmental interest, and leave open ample alternative channels for communication of the information. Id. (internal quotation marks and citations omitted). In this “intermediate scrutiny” context, by “narrowly tailored to serve a significant governmental interest,” id., we do not mean to imply that a regulation must be “ ‘the least restrictive or least intrusive means of [achieving the stated governmental interest],’ ” id. (quoting Ward v. Rock Against Racism, 491 U.S. 781, 798, 109 S.Ct. 2746,105 L.Ed.2d 661 (1989)). Rather, “[t]he narrow tailoring requirement is satisfied so long as the ... [content-neutral] regulation promotes a substantial governmental interest that would be achieved less effectively absent the regulation.” Id. (emphasis added) (internal quotation marks omitted). A content-neutral “time, place or manner” restriction will be considered narrowly tailored unless “a substantial portion of the burden on speech does not serve to advance its goals.” Ward, 491 U.S. at 799, 109 S.Ct. 2746. “Government regulation of expressive activity is content neutral so long as it is justified without reference to the content of the regulated speech.” Hobbs, 397 F.3d at 149 (internal quotation marks omitted). Provided that a regulation “serves purposes unrelated to the content of expression,” it will be deemed content-neutral, “even if it has an incidental effect on some speakers or messages but not others.” Ward, 491 U.S. at 791, 109 S.Ct. 2746. Regulations that target “only [the] potentially harmful secondary effects of speech” are therefore content-neutral and trigger intermediate, rather than strict, scrutiny. Hobbs, 397 F.3d at 150. The District Court, in reviewing plaintiffs’ First Amendment claims, improperly truncated its analysis, resting its holding almost exclusively on its finding that plaintiffs’ sale of artistic items qualifies as protected speech and paying less attention to the equally important question of whether § 20-453 is a valid “time, place or manner” restriction. Tellingly, the District Court inquired whether plaintiffs’ items “possess sufficiently expressive qualities to qualify for First Amendment protection and thereby become exempt from the Ordinance’s licensing requirement.” Mastro-vincenzo, 313 F.Supp.2d at 286 (emphasis added). The District Court’s only discussion of the validity of § 20-453 consisted of the following paragraph: The City’s licensing requirement was intended to catch within its net merchants engaged solely in commerce of ready-made goods that clog the sidewalks and compete unfairly with legitimate stores. Applied overbroadly, as Defendants would do, the Ordinance essentially would impose a chilling effect on genuine artists whose true calling is art and not commerce, and whose manifest purpose may be to create expression rather than markets, even if at times some of their work may skirt the line between expressiveness and merchandise. Such an extension of the licensing regime would force artists to confront an undue dilemma: either to quell their creativity or to risk arrest if they believe their work is sufficiently expressive to fall within the protection of the First Amendment. Freedom of expression is designed precisely to bar the government from compelling individuals into that speech-inhibiting choice. Icl. at 292-93. Whatever rationale the District Court may have used in reaching its conclusion that § 20-453 is “[a]pplied over-broadly,” we disagree with its conclusion. We begin with the observation that New York City’s licensing requirement is clearly a content-neutral speech restriction because it “serves purposes unrelated to the content of [the regulated] expression,” Hobbs, 397 F.3d at 150 (internal quotation marks omitted), namely: (1) keeping the public streets free of congestion for the convenience and safety of its citizens, (2) maintaining the “tax base and economic viability of the City,” and (3) preventing the sale of “stolen, defective or counterfeit merchandises,” see Mastrovincenso, 313 F.Supp.2d at 283 (quoting New York City Local Law 40/1988 § 1). While § 20-453 undoubtedly has “incidental” or “harmful secondary effects” on plaintiffs, these do not render the regulation content-based because it may still be “justified without reference to the content of the regulated speech.” Hobbs, 397 F.3d at 149 (internal quotation marks omitted). The mere fact that New York City differentiates between categories of vendors — that is, vendors of written materials, paintings, photographs, prints and sculptures are exempt from its licensing requirement while other vendors are not— does not suggest that the City’s regulation targets particular messages and favors others. Nor does § 20-453 “confer unbridled discretion on the licensing authority” enabling that authority “to favor some speakers while suppressing others.” White v. City of Sparks, 341 F.Supp.2d 1129,1141 (D.Nev.2004) (internal quotation marks and citation omitted). Unlike a licensing scheme in which “there are no limiting criteria or standards” for when a license will be required, cf id. at 1142 (striking down a city regulation that makes licensing requirements contingent on a city official’s determination of whether a particular painting “conveys a religious, political, philosophical or ideological message”) (internal quotation marks omitted), New York City’s licensing requirement applies across the board to all non-exempt vendors, ie. vendors whose goods and services are neither food items, written materials, or items specifically mentioned in the Bery injunction (paintings, photographs, prints and sculptures). Furthermore, plaintiffs do not allege any discriminatory enforcement against certain non-exempt vendors based on the content of their art. There can be no doubt that New York City’s avowed objectives in enforcing its licensing requirement, such as reducing sidewalk and street congestion in a city with eight million inhabitants, constitute “significant governmental interests.” Nor have plaintiffs or the District Court denied that a fixed-ceiling licensing requirement represents a “reasonable” means of controlling that congestion. The dispositive issue, therefore, is whether the significant governmental interests that § 20-453 promotes “ ‘would be achieved less effectively absent the regulation/ ” Ward, 491 U.S. at 799, 109 S.Ct. 2746 (quoti
