Provenance & Authentification

We offer certificates of authenticity at a cost of $50 each certificate. This will also add you to the Guirado Estate database for provenance records that are often required for sales on the secondary market. 

We are happy to help sell works belonging to collectors but offer no guarantee and will take a  pre-agreed commission. We also offer consultation on the current art market.


Any paintings that are submitted to an auction without a prior certificate of authenticity and provenance from the Guirado Estate will not be authenticated as works of Juan Antonio Guirado's. 

Auction houses or Galleries please contact us for our provenance records of sales and official valuation of paintings by Pablo Melendo Consultation ES.
