Immediately upon the receipt of the license certificate issued by the city, 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, subagency, 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 chief of police or an authorized representative of the police department. No person holding such license certificate shall post such certificate or 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 article or knowingly alter, deface or destroy any such license certificate. Every license certificate shall be surrendered to the chief of police within 72 hours after its terms shall have expired or after notice in writing to the holder that such license has been revoked. Failure to comply with any provisions of this section is a misdemeanor and sufficient cause for the revocation of a license. (Ord. 4039)
