Whenever an art dealer furnishes the name of the artist pursuant to Section 1744 for any time period after 1949, and otherwise furnishes information required by any of the subdivisions of Section 1744 for any time period, as to transactions including offers, sales, or consignments made to other than art dealers, and to other art dealers, such information shall be a part of the basis of the bargain and shall create express warranties as to the information provided. Such warranties shall not be negated or limited because the art dealer in the written instrument did not use formal words such as “warrant” or “guarantee” or because the art dealer did not

have a specific intention or authorization to make a warranty or because any required statement is, or purports to be, or is capable of being merely the seller’s opinion. The existence of a basis in fact for information warranted by virtue of this subdivision shall not be a defense in an action to enforce such warranty. However, with respect to photographs and sculptures produced prior to 1950, and other multiples produced prior to 1900, as to information required by paragraphs (3), (4), (5), and (6) of subdivision (a) of Section 1744, the art dealer shall be deemed to have satisfied this section if a reasonable basis in fact existed for the information provided. When information is not supplied as to any subdivision or paragraph of Section 1744 because not applicable, this shall constitute the express warranty that the paragraph is not applicable.

Whenever an art dealer disclaims knowledge as to a particular item about which information is required, such disclaimer

shall be ineffective unless clearly, specifically, and categorically stated as to the particular item and contained in the physical context of other language setting forth the required information as to a specific multiple.
