§ 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.
