Verify a certificate
Enter the number printed on the certificate, or scan the seal. The register returns the artist's own record for that work.
Certificate number
How it works
- Numbered at completion
Every finished work gets a catalogue reference and a certificate number before it leaves the studio.
- Signed and sealed
The certificate carries the artist's signature and a holographic seal whose code resolves to this page.
- Recorded
Title, date, dimensions, materials and status are held in the register and returned by the check above.
- Transferred on resale
The certificate travels with the work and the register is updated, so the chain stays unbroken.
