(a) The rights, liabilities, and remedies created by this part shall be construed to be in addition to and not in substitution, exclusion, or displacement of other rights, liabilities, and remedies provided by law.

(b) Whenever an artist sells or consigns a multiple of his own creation, the artist shall incur the obligations prescribed by this part for an art dealer.

(c) An artist or merchant who consigns a multiple to an art dealer for the purpose of effecting a sale of the multiple shall have no liability to a purchaser under this part if such consignor, as to the consignee, has complied with the provisions of this part.

(d) When an art dealer has agreed to sell a multiple on behalf of a consignor who is not an art dealer or when an artist has not consigned a multiple to an art dealer, but the art dealer has agreed to act as the agent for an artist for the purpose of supplying the information required by this part, such art dealer shall incur the liabilities of other art dealers prescribed by this part as to a purchaser.

(e) When an art dealer is liable to a purchaser pursuant to the provisions of this part, as a result of providing information in the situations referred to in this Code section, as well as when such an art dealer purchased such a multiple from another art dealer, if the art dealer can establish that his liability results from incorrect information which was provided by the consignor, artist, or art dealer to him in writing, and the art dealer who is liable in good faith relied on such information, the consignor, artist, or art dealer shall similarly incur such liabilities as to the purchaser and such art dealer.
