Section 15.13. Construction

1. The rights, liabilities and remedies created
  by  this  article  shall  be  construed  to be in addition to and not in
  substitution, exclusion or displacement of other rights, liabilities and
  remedies provided by law, except where such  construction  would,  as  a
  matter of law, be unreasonable.
    2.  Whenever  an  artist  sells  or  consigns  a  multiple  of his own
  creation, the artist shall incur  the  obligations  prescribed  by  this
  article  for  an  art  merchant,  but  an  artist shall not otherwise be
  regarded as an art merchant.
    3. An artist or merchant who consigns a multiple to a merchant for the
  purpose of effecting a sale of the multiple shall have no liability to a
  purchaser under this article if such consignor, as to the consignee, has
  complied with the provisions of this article.
    4. When a merchant has agreed to  sell  a  multiple  on  behalf  of  a
  consignor,  who  is  not  an  art  merchant,  or  when an artist has not
  consigned a multiple to a merchant, but the merchant has agreed  to  act
  as  the agent for an artist for the purpose of supplying the information
  required by this article, such merchant shall incur liabilities of other
  merchants prescribed by this article as to a purchaser.
    5. When an art merchant or merchant is liable to a purchaser  pursuant
  to  the provisions of this article, as a result of providing information
  in the situations referred to above in this section,  as  well  as  when
  such  a merchant purchased such a multiple from another merchant, if the
  merchant or art merchant can establish that his liability  results  from
  incorrect  information  which  was  provided by the consignor, artist or
  merchant to him in writing, the merchant who is  liable  in  good  faith
  relied  on  such  information,  the  consignor, artist or merchant shall
  similarly incur such liabilities as to the purchaser and such merchant.
