How to Identify an Unknown Painting: Signatures, Labels, Provenance, and Expert Help

Finding an unsigned or unfamiliar painting raises one question: who made it? Identifying a work means reading its signature, labels and physical clues, tracing its provenance, and knowing when to call in a professional appraiser or conservator for a confident answer.

Questions and Answers

Where do I start when identifying an unknown painting?

Examine the front and back carefully. Look for a signature or monogram in a corner, gallery or framer’s labels on the back, inscriptions, stamps or a date. Photograph everything in good light before researching further.

What can the back of a painting tell me?

The reverse often holds more clues than the front: auction house stickers, exhibition labels, customs stamps, canvas or panel manufacturer marks, and old inventory numbers. Avoid cleaning or removing anything from the back before it has been examined.

How do I research a signature I can’t read?

Compare it against published signature dictionaries and artist databases, or search close-up photos online. A conservator or appraiser can often narrow down a hand, region or period even when a name stays illegible.

What is provenance and why does it matter?

Provenance is the documented chain of ownership of a work, from the artist’s studio to today. Bills of sale, exhibition catalogs and estate records help confirm authorship, and can affect value; gaps are common but worth noting. See our guide to art appraisals for how value and documentation connect.

When should I call in a professional?

If a painting looks old, skillfully made or potentially valuable, a qualified appraiser or conservator can examine materials, technique and condition, and advise on authentication, cleaning or insurance. Our guide to spotting reproductions covers a related first check you can do yourself.
