2006 New York Code - Licenses To Be Displayed.

 
    §  20-304  Licenses  to  be  displayed. Every licensed locksmith shall
  display the license issued hereunder in a conspicuous place where it can
  be readily seen by anyone entering the premises where  the  business  is
  conducted.  Where  the licensed locksmith is not in business for himself
  or herself but is employed by another, it shall be  incumbent  upon  the
  licensee  and  his or her employer to display the license hereunder in a
  conspicuous place where it can be readily seen by  anyone  entering  the
  premises  wherein  the  business  is  conducted.  Where  more  than  one
  locksmith is employed in such premises the license of the person then in
  charge need only be displayed. In the case of an itinerant locksmith the
  license shall be on his or her person or prominently displayed upon  the
  working  kit he or she may carry or upon any vehicle which he or she may
  use in the plying of his or her trade or occupation.
