Authenticity Guarantee


All paintings, photographs, prints {lithographs, etchings, serigraphs etc.}, and sculptures sold by Mantissa Art are guaranteed by us to be a genuine work of the artist listed.

However, in the unlikely event that any artwork purchased from Mantissa Art is subsequently proven to be unauthentic, we will refund the full purchase price and shipping costs paid by you. These cases will be handled on a case-to-case basis and require examinable proof of questionable authenticity to be provided by an established authority mutually acceptable to Mantissa Art and the buyer.

We provide a lifetime money back guarantee on the authenticity of artworks purchased from us if:

  • The actual buyer makes the claim (The benefit of the claim is not assignable to any other person).
  • The item is returned in the same condition that it was purchased in.
  • The item was indisputably purchased from Mantissa Art
