Real client case
Real client case reviewed by ConfirmArt for "da Leonardo da Vinci / MA.", attributed or related to Historic & Old Master Cases. The public page presents selected visual evidence and a rendered report viewer without exposing the private commissioned PDF.
Selected evidence
Report structure
Entire printed plate photographed out of its mount, frame excluded for clarity. The object is a small, jewel-like print on laid paper ( sheet c. 195 × 175 mm; plate-mark 153 × 137 mm) executed predominantly in etching with selective burin touches to sharpen contours and deepen the principal shadows.
Authentication evidence
Private authentication
Use this real case as a reference for the kind of evidence that can be organized in a private authentication report.
Public report viewer
The public browser receives rendered pages, not a native PDF viewer or direct PDF URL. Public pixels can still be screen-captured; private commissioned reports remain controlled client deliverables.
QR verification
This real case has a stable verification URL and source fingerprints. The QR code resolves to the public verification record for this case.

Only your email and service selection are needed to submit the request. Optional images, dimensions and notes can be added now or later.
Payment is requested only for the Authentication report. Catalogue search, advisory, restoration and local inspection requests are reviewed first so the scope can be confirmed.
Authentication is a human expert review. ConfirmArt may use AI for bounded research support such as database, image, book or provenance searches, but not as a classifier verdict.
