How to identify a painting
To identify a painting, work out what it is physically (medium and support), when and where it was probably made (period and school), and only then who made it (signature, labels and documented comparisons). Each clue narrows the field, and an identification is only as strong as the evidence that agrees with it.
What evidence identifies a painting?
The most useful evidence is physical and visible: the medium, the support, the signature and any inscriptions, the labels and stamps on the back, and the style and subject. Family stories and price tags help, but they are leads to test rather than proof.
Medium
Oil paint sits in raised, glossy strokes and often shows fine age cracks (craquelure). Watercolor is transparent and lets the paper show through; gouache is matte and opaque; acrylic dries flat with a slightly plastic sheen and rarely cracks in the same way. Pastel leaves a powdery surface, usually under glass.
Support
Canvas, wood panel, copper, paper, academy board, or hardboard. Hardboard such as Masonite was only introduced in the mid-1920s, so a painting on it cannot be an eighteenth-century work, whatever the style suggests.
Signature and inscriptions
A name, initials, monogram, date or place, usually in a lower corner. Note its position, color and whether it sits inside the paint layer or on top of the varnish.
The back (verso)
Canvas stamps from artists' suppliers, gallery and exhibition labels, auction stencils, framers' labels, handwritten titles and old inventory numbers often say more than the front.
Style, subject and technique
Broken color and visible strokes point toward Impressionism or its followers; smooth glazes and tight detail toward academic or earlier traditions; a palette knife impasto toward the mid-twentieth century. Subjects also date: a coastal scene with steamships is later than one with only sail.
Frame and construction
Stretcher bars with corner keys, hand-cut nails, tacks versus staples, and the profile and gilding of the frame each have a history. Frames are often replaced, so they support a date rather than prove one.
How do you identify a painting step by step?
Start with what you can observe without guessing, record it, and move from the general (medium, period) to the specific (artist). Writing each observation down stops a hopeful reading of the signature from steering everything else.
Photograph and measure it
Take a straight, evenly lit photo of the front, close-ups of the signature and any detail that looks unusual, and the full back with the frame on and off if that is safe. Measure the image size, not just the frame.
Identify the medium and support
Look at the surface in raking light and at the edges of the canvas or panel. Decide whether it is an original painting or a print, and whether it is oil, acrylic, watercolor, gouache or a mixed technique.
Check whether it is a reproduction
Use a 10x loupe. A regular pattern of tiny colored dots means a photomechanical print. Brushstrokes that sit on top of a flat printed image suggest an embellished reproduction, common in the decorative market since the 1980s.
Transcribe everything written on it
Copy the signature letter by letter, plus every label, stamp and pencil note on the back, even if they seem irrelevant. A framer's address or a colorman's stamp can date the painting within a few decades.
Place it in a period and school
Compare the style, subject and technique with museum collections. Ask what kind of painting this is (a Barbizon-type forest scene, a Hudson River School landscape, a Dutch-style genre interior, a mid-century abstraction) before asking who painted it.
Build a shortlist of artists
Search candidate names from the signature in artist dictionaries such as the Getty Union List of Artist Names, and keep only those whose dates, nationality and typical subjects fit what you established in the previous steps.
Compare with documented works
Look at signed, dated paintings by each candidate in museum databases and auction archives. Compare the handling of paint, the way the signature is formed and the subjects, not just the general look.
Grade your conclusion
Decide whether the evidence supports a firm attribution, a probable one, an attribution to a circle or school, or only a period and region. A carefully graded conclusion is more useful than a confident guess.
What do useful identification clues look like?
Useful clues are specific, checkable and independent of each other. Here are typical cases where a single detail moved an identification forward.
A supplier's stamp on the canvas
A stamp reading "Lefranc, Paris" or "Winsor & Newton, 38 Rathbone Place" on the back of the canvas tells you where the canvas was bought and gives a likely date range, which can confirm or contradict an attribution to a French or British artist of a particular generation.
An exhibition label
A label from the Royal Academy summer exhibition, the Paris Salon or the Pennsylvania Academy of the Fine Arts annual gives a title, sometimes an artist and an address, and a year. Exhibition catalogs are often digitized, so the entry can be checked.
A monogram rather than a name
James McNeill Whistler signed with a stylised butterfly; Henri de Toulouse-Lautrec often used an HTL monogram in a circle. Monograms are harder to read but, once matched, are highly characteristic of an artist.
A subject that dates the scene
Costume, hairstyles, vehicles, and buildings give a date after which the painting must have been made. A street scene with motorcars cannot predate the twentieth century, whatever the signature says.
A support that rules something out
An "Old Master" on hardboard, or a supposedly 1880s painting on canvas board with a printed supplier's label from the 1950s, is immediately revisable. Negative evidence is as valuable as positive evidence.
What are the most common mistakes when identifying a painting?
Most mistakes come from trusting one clue too much, usually the signature or a resemblance to a famous artist, and from damaging evidence before it has been recorded.
Starting with the most famous name
A loose, colorful landscape is not a Monet because it looks a little like one. Thousands of painters worked in Impressionist styles; the right question is which of them the evidence supports.
Treating the signature as proof
Signatures were added, copied and misread. A signature is one clue to be tested against medium, period and style, not a conclusion.
Cleaning or removing labels
Household cleaners can strip glazes and varnish. Peeling off an old label to read it can destroy it. Record first, and leave cleaning to a conservator.
Ignoring the back
Many owners photograph only the front. The verso often holds the most precise dating evidence and the only provenance.
Confusing a print with a painting
Varnished prints on canvas and textured reproductions can fool the eye at arm's length. A loupe and a look at the edges settle the question quickly.
How can Veriso help?
Veriso follows the same order as this method. From your photographs of the front, the signature and the back, it describes the medium and technique, suggests a likely period and school, reads and transliterates the signature, transcribes labels and inscriptions, and then tests candidate artists against all of that evidence rather than against the signature alone.
The report states how strong each part of the identification is, from a firm reading to a broad regional attribution, and explains what further evidence would change it. When the evidence supports a market estimate, it is shown as a range drawn from comparable sales. It is a research starting point that you can take to an auction house specialist or a qualified appraiser.
What is Veriso?
Veriso is an artwork investigation tool: it analyzes photographs of a painting or other artwork alongside the evidence that identifies it — subject, medium, technique, likely period and school, signatures, and verso labels — and sets out which attributions that evidence supports.
Veriso's findings are research, not a certificate: it does not authenticate artworks or replace a formal appraisal, and its market estimates are indicative ranges based on comparable sales. How Veriso works
Frequently asked questions
Can I identify a painting from a photo?
Often, yes, at least to a medium, period and school, and sometimes to an artist. Clear photographs of the front, the signature and the back carry most of the visible evidence. Physical tests such as paint sampling or UV examination still require the object itself.
How do I find out who painted a picture?
Read and transcribe the signature, then search the possible readings in artist databases and filter the results by period, nationality and subject. Confirm by comparing your painting with signed and dated works by each candidate.
What if the painting has no signature?
Many paintings were never signed. Identification then relies on the back, the materials, the style and any provenance. Expect a conclusion such as "French school, about 1870" rather than a name, unless strong documentary evidence exists.
How can I tell if a painting is an original?
Look for raised brushstrokes, uneven paint edges, and the absence of printed dot patterns under magnification. Check the canvas edges: an original painting usually has paint running onto the tacking margins, while a print is often flat and trimmed.
Is identifying a painting the same as authenticating it?
No. Identification establishes what the evidence supports about a painting. Authentication is a formal opinion, usually from the recognized expert or catalogue raisonné committee for a specific artist, and it is what the market relies on for important works.
