Pennsylvania Statutes Title 22 P.S. Detectives § 18. Posting and surrender of license certificate

Immediately upon the receipt of the license certificate issued by the court of quarter sessions pursuant to this act, the licensee named therein shall cause such license certificate to be posted up and at all times displayed in a conspicuous place in the bureau, agency, sub-agency, office or branch office for which it is issued, so that all persons visiting such place may readily see the same. Such license certificate shall, at all reasonable times, be subject to inspection by the district attorney or an authorized representative or representatives of the Pennsylvania State Police and the Attorney General. It shall be unlawful for any person, partnership, association or corporation holding such license certificate to post such certificate, or to permit such certificate to be posted, upon premises other than those described therein, or to which it has been transferred pursuant to the provisions of this act, or knowingly to alter, deface or destroy any such license certificate. Every license certificate shall be surrendered to the court of quarter sessions within seventy-two hours after its term shall have expired, or after notice in writing to the holder that such license has been revoked. Any licensee failing to comply with any of the provisions of this section shall be guilty of a misdemeanor, and, upon conviction thereof, shall be sentenced to pay a fine of not more than five hundred dollars ($500) or to under go imprisonment for not more than (1) year, or both. Such failure shall be sufficient cause for the revocation of a license.
