City code prohibits such displays on public property:

Sec. 19-22. Posting of signs or advertising prohibited.
It shall be unlawful for any person to paint, mark or write on, or post or otherwise affix to or upon a public way or
fixture thereon any sign or other form of commercial, noncommercial, or political advertising, promotion, solicitation,
communication, or display. It shall furthermore be unlawful for any person, firm, or corporation to cause or,
with knowledge, permit such actions to be taken on such person’s or firm’s or corporation’s behalf.
(Ord. No. 85-305-283 (3-41), 12-16-85)

Sec. 19-24. Removal of signs or advertising; collection of costs of removal.
Any violation of this article is hereby declared to be a nuisance. No person shall have any legal right to the continued
presence of a sign in a public way in violation of this article; nor shall there be any legal remedy against any
person solely for the removal from a public way of a sign which is in violation of this article. Any person may abate
the nuisance created by a violation of this article without liability for doing so. In the event that abatement is made by
the City, the reasonable costs incurred in removal may be assessed against any person, firm, or corporation responsible
for or benefited by the violation, and such costs shall be collected in the same manner as City taxes. In the event
of a willful violation, the City shall be entitled to recover costs, the reasonable value of attorney’s fees, and punitive
damages in any proceeding which it may bring to enjoin future violations.
(Ord. No. 85-305-283 (3-43), 12-16-85; Ord. No. 92-71-73, § 2, 4-13-92)
Sec. 19-25. Penalty for violation.
Any person convicted of a violation of Section 19-22 shall be punished by a fine of not less than ten dollars ($10.00)
and not more than fifty dollars ($50.00) for each offense, and each individual sign or other form of commercial,
noncommercial, or political advertising, promotion, solicitation, communication or display, shall be deemed a
separate offense. Each day during which any such violation is continued may be treated for all purposes as a separate
offense.
(Ord. No. 85-305-283 (3-44), 12-16-85)
