Authenticate
Is it a true Verdult? Then make it permanent.
Two steps. First the Estate tells you whether your painting is a strong candidate. Then it is certified and recorded on the blockchain.
Initial Estate Review
Send photos and any provenance you have. The Estate checks it against its records and sends a written determination: is it a strong candidate for certification?
$198 per piece, nonrefundable
Start Step 1Certify and put it on the blockchain
If Step 1 supports it, you receive a Certificate of Authenticity, a provenance file, an Estate Authentication and Certification Record, an Estate-supported value opinion, and a Verisart blockchain registration. Your piece is added to the public Provenance Registry.
$395 standard · $295 for returning Step 1 clients · collections as low as $195 per piece

Ask William about his work, or look at what Verdult originals have sold for.
★ Ask William See auction prices
Prices are from the Authentication Program page on this store. Ask William never says whether a painting is real or what it is worth. Only the Estate does that, in Step 1 and Step 2.
