Free artist signature identification app

One clear answer

Start with clear photos of the signature, then check medium, subject, paper or canvas, labels, edition, frame, condition, and whether the style supports the name.

Need a value you can share with family, a buyer or an estate? An online art appraisal works from your photos and recent comparable sales, and ends in a signed report from $59.

Auction records are market evidence, not a final appraisal. Condition, authenticity, provenance, size, medium, edition, subject, and demand can materially change value.

Photo checklist

• Photograph the whole artwork, signature, initials, date, edition, labels, back, stretcher, frame, and any inscriptions.
• Use sharp, glare-free close-ups from straight on and at a slight angle.
• Do not trace, darken, clean, or repaint a signature before review.

What changes the answer

• A signature matters only when medium, style, date, provenance, and condition support it.
• Pencil-signed prints, signed posters, signed paintings, and estate stamps have different standards.
• Unknown or illegible signatures can still be appraised by quality, medium, subject, and comparables.
