Section 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.
