Certificates of authenticity for drawings
Drawings are often the first works to lose their paperwork and the hardest to attribute years later. Attesian fixes the record at the source: register a drawing and it gets a signed certificate and a permanent, append-only history from day one.
The certificate confirms the maker and the work; the provenance record captures everywhere the drawing goes next. Both are verifiable by anyone with the QR code, without an account.
A genesis event pins authorship at the start, which matters most for works on paper that move quietly between hands.
Studies, sketches, and finished drawings can each hold their own record and certificate.
Every later event is added, never overwritten — so the history only grows more complete.
How image fingerprinting applies
As a flat medium, a drawing takes a strong perceptual image fingerprint in its certificate, tying it to a specific photograph and flagging substitution. It captures the whole sheet as one image, so it is a work-level check rather than proof of physical condition.
Questions
- Can I certify a drawing that isn't for sale?
- Yes. A certificate and provenance are useful from day one — for insurance, loans, estate records, or simply establishing authorship — long before a work is ever sold.
