Section 586. Substitution, addition and commingling of goods; license void; certain purchases prohibited

(a) Any substitution for  or  addition  to
  goods  described  in an inventory filed pursuant to this article, or any
  change in the time or place of a sale conducted pursuant thereto,  shall
  be  unlawful and any license issued for such sale shall thereupon become
  void.
    (b) Where an applicant, conducting a sale licensed under this article,
  also conducts a business of selling other goods,  wares  or  merchandise
  not  included  in the inventory accompanying the application, the goods,
  wares and merchandise to be sold at  such  sale  shall  be  clearly  and
  distinctly  segregated, marked or identified, and advertised, if at all,
  so that, both on display and  in  advertising,  such  goods,  wares  and
  merchandise  may  be  readily  distinguished from other goods, wares and
  merchandise and their identity readily ascertained. Any  commingling  of
  such   goods,   wares  and  merchandise  with  other  goods,  wares  and
  merchandise of the licensee in such a manner as to cause  them  to  lose
  their  separate  identity, either on display or in advertising, shall be
  unlawful and any license issued pursuant for such sale  shall  thereupon
  become void.
