Michigan Compiled Laws, Chapter 442. Sales § 442.363

Sec. 13. If for purposes of effecting the sale of a multiple, an art merchant has agreed to act as the agent for a consignor who is not an art merchant, or if for purposes of supplying the information required by this act, an art merchant has agreed to act as the agent for an artist, the art merchant shall incur the liabilities prescribed by this act with respect to a purchaser. However, if the art merchant can establish that his or her liability results from incorrect information which was provided to the art merchant in writing by the consignor or artist, and that the art merchant in good faith relied on the information, the consignor or artist shall similarly incur the liabilities with respect to the purchaser and the art merchant.
