When artists sell their work, they must provide a Certificate of Authenticityin order to be more professional and give all the guarantees to the buyer. A Certificate of Authenticity is essential for the attribution of a work.
Without a Certificate of Authenticity, it's impossible to determine the artwork's origin or to attribute it to an artist. The only value it has will depend on its size, the technique, the materials, and the subject represented.
A Certificate of Authenticity is the key to the successful sale of your works. You must provide a Certificate of Authenticity to the buyer (even if he or she does not ask for one) along with the invoice.
Without a Certificate of Authenticity, most doors will remain closed; no estimate, no transaction. A Certificate of Authenticity is mandatory to establish that a work of art is authentic and has been created by the Artist.
No mention in a raisonné catalog about the financial value of the artwork. Without a Certificate of Authenticity, it's impossible to evaluate the artwork, its only value depends on its size, its technique, the materials used and the subject represented.
