Originals, Art archives and Artwork Authenticity
------------------------------------------------------
Before buying an artwork, it is appropriate to verify its provenance and authenticity. If the artwork is not included in the latest and most comprehensive Catalogue Raisonné of the artist and if there is no the the Certificate of Authenticity issued to the owner, you have a problem!

You should ask for a CERTIFICATE OF AUTHENTICITY, Artwork archiving number, and relative bibliography if existent. In the case that purchased artwork is not accompanied with the CERTIFICATE OF AUTHENTICITY, it is convenient to obtain it directly from the artist, if living, or from the foundation's experts and scientific committee, or from the art archive which is protecting the artistic heritage of the artist.

For the protection against acquisition of fake, counterfeited artwork or of dubious origin, the certificate of authenticity is the only way to protect investments.

Those who are approaching to the world of art, both collectors and enthusiasts, it is of fundamental importance to re-control the validity of their CERTIFICATE OF AUTHENTICITY, by well known established authority for the artist in question.

There is also the existent legislation on cultural heritage which impose on those who trade paintings, sculpture, graphics, objects of antiquity or objects of historical or archaeological interest, to release time of sale of a photographic copy of the artifact with the written statement of authenticity and an indication of the origin.

Case study: Picasso Authentication
-----------------------------------------
Do yu have a Picasso, with a certificate of Gallery XY, famous gallery in London?
What is the value of that ridiculous certificate of authenticity? NOTHING!!

If the drawing is not included in the latest and most comprehensive catalogue raisonné, The Picasso Project edited by Wofsy, or in old Zervos catalogue, the only alternative to establish value today is to obtain a signed photocertificate of authenticity from Maya Widmaier Picasso and/or Claude Picasso. They are two of his children and the only people in the world who have the legal authority to authenticate his unique works. Marina Picasso, one of his grandchildren, has sold a part of her inheritance and generally has a stamp that bears her name on the back of her prints and works on paper. But her Picassos are typically already catalogued. Unlike Maya and Claude, she doesn’t authenticate works that have surfaced and been brought to her attention. Without inclusion in at least one catalogue raisonné or authentication by Maya or Claude, the authenticity of the drawing can’t be proved and it becomes impossible to sell for anything close to the value it would command if it were real, unless the seller finds an unsuspecting newbie collector who is prepared to make a costly mistake without engaging in the most basic due diligence.
