How to identify old paintings
Old painting identification starts with medium, surface, back, signature, labels, frame, age clues, condition, and provenance. Age alone is not enough.

Start by deciding whether the work is oil, watercolor, acrylic, gouache, pastel, print, reproduction, or mixed media. Then document the back and condition before assuming artist or value.
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
- Medium, artist, subject, quality, condition, provenance, and demand drive the next step.
- Back labels, stretcher marks, canvas, panel, paper, frame, and inscriptions can be more useful than the front alone.
- Dirty varnish, overpaint, tears, fading, and poor framing can change both identification and value.

Condition and authenticity cautions
Do not clean, reframe, remove labels, or touch paint surfaces before documentation. Those details may be the best evidence.
Use a professional appraisal or authentication path when artist attribution, legal use, insurance, donation, or a significant sale is involved.
