§ 13.05. Express warranties for multiples. 1. When an art merchant furnishes the name of the artist of a multiple, or otherwise furnishes information required by this title for any time period as to transactions including offers, sales or consignments, the provisions of section 13.01 of this article shall apply except that said section shall be deemed to include sales to art merchants. The existence of a reasonable basis in fact for information warranted shall not be a defense in an action to enforce such warranty, except in the case of photographs produced prior to nineteen hundred fifty, and multiples produced prior to nineteen hundred.

2. The provisions of subdivision four of section 13.01 of this article shall apply when an art merchant disclaims knowledge as to a multiple about which information is required by this title, provided that in addition, such disclaimer shall be ineffective unless clearly, specifically and categorically stated as to each item of information and contained in the physical context of other language setting forth the required information as to a specific multiple.
