Section 18. License to operate moving picture apparatus

It shall not be
  lawful for any person or persons, save as excepted in section eighteen-a
  of this article,  to  operate  any  moving  picture  apparatus  and  its
  connections  in  a city of the first class unless such person or persons
  so operating such apparatus is duly licensed  as  hereinafter  provided.
  Any person desiring to act as such operator shall make application for a
  license  to so act to the mayor or licensing authority designated by the
  mayor, unless the charter of said  city  so  designates,  which  officer
  shall  furnish  to  each  applicant blank forms of application which the
  applicant shall fill out. Such officer shall make rules and  regulations
  governing the examination of applicants and the issuance of licenses and
  certificates.  A  license shall not be granted to an applicant unless he
  shall have served as an apprentice under  a  licensed  operator,  for  a
  period of not less than six months prior to the date of the application;
  the  application  must  be  made  in  writing,  and  contain  a verified
  statement to that effect; it must be accompanied by the affidavit of the
  licensed operator to the same effect; before entering upon the period of
  apprenticeship the applicant must register his name and address with the
  officer issuing such license. The applicant shall be given  a  practical
  examination  under  the  direction of the officer required to issue such
  license and if found competent as  to  his  ability  to  operate  moving
  picture  apparatus  and  its  connections  shall receive within six days
  after such examination a license as herein provided. Such license may be
  revoked or suspended at any time by the officer issuing the same.  Every
  license shall continue in force for one year  from  the  date  of  issue
  unless  sooner  revoked  or  suspended. Every license, unless revoked or
  suspended, as herein provided, may at the end of one year from the  date
  of  issue thereof be renewed by the officer issuing it in his discretion
  upon application and with or  without  further  examination  as  he  may
  direct. Every application for renewal of license must be made within the
  thirty  days  previous  to  the expiration of such license.   With every
  license granted there shall be issued to  every  person  obtaining  such
  license  a certificate, certifying that the person named therein is duly
  authorized to operate moving picture apparatus and its connections. Such
  certificate shall be displayed in a conspicuous place in the room  where
  the  person  to  whom it is issued operates moving picture apparatus and
  its connections. No person shall be eligible to procure a license unless
  he shall be of full age. Any person offending against the provisions  of
  this  section, as well as any person who employs or permits a person not
  licensed as herein provided to operate moving picture apparatus and  its
  connections,  shall  be  guilty  of  a  misdemeanor  and upon conviction
  thereof shall be punished by a fine not exceeding the sum of one hundred
  dollars, or imprisonment for a period not  exceeding  three  months,  or
  both.
