What is a Certificate of Authenticity for a Portinari artwork, and how do you obtain one?
The Certificate of Authenticity is the official document issued by the Portinari Project after the artwork has been evaluated and approved by our specialized committee, thus guaranteeing its inclusion in our catalog. If you own a work attributed to the painter that is not yet cataloged or does not have certification, please contact us through the "Contact" section of this portal or directly by email at noelia@portinari.org.br.
