How to identify bronze sculpture marks
Bronze sculpture marks can include artist signatures, foundry stamps, edition numbers, inscriptions, plaques, copyright marks, and later labels. They need to be read with the sculpture itself.

Start with the base, underside, back, side, plaque, edition number, foundry mark, patina, casting quality, and provenance. A mark is evidence, not proof by itself.
Auction records are market evidence, not a final appraisal. Condition, authenticity, provenance, size, medium, edition, subject, and demand can materially change value.
Evidence checklist
- Photograph the whole object, close details, back, frame or base, signatures, labels, condition issues, and scale.
- Include medium, dimensions, provenance, receipts, certificates, gallery labels, and prior appraisal records.
- Show the evidence that could prove or disprove the first assumption: texture, paper, canvas, plate mark, edition, foundry mark, surface, or damage.
What changes the answer
- Artist signature, foundry, edition, casting quality, patina, subject, and provenance affect value.
- After-casts and reproductions can carry marks that require close review.
- Polishing, repainting, repairs, and missing bases can affect both marks and value.
