How to Identify a Signed and Numbered Print
A pencil signature and edition fraction can be useful evidence, but neither should be evaluated in isolation. Identification comes from comparing the whole object with reliable records for the edition.
Hand signature or signature in the image?
View the mark under magnification and changing light. A hand-applied pencil or ink line generally sits on the paper surface and may show pressure or variation. A signature reproduced as part of the image has the same dot, ink or printing character as the surrounding design. Some legitimate editions use stamped or printed signatures, so the expected signing practice for that edition matters.
Read the edition fraction correctly
In 25/250, the first number identifies that impression and the second normally states the numbered edition size. The fraction does not mean the print is the twenty-fifth one pulled, and lower impression numbers are not automatically earlier, better or more valuable.
Compare more than the signature
Check the sheet dimensions, paper, margins, image orientation, publisher or printer marks and placement of the signature and number. Compare those details with a catalogue raisonné, publisher documentation, museum record or well-catalogued sale. A plausible signature on the wrong paper or wrong-sized image is a reason for more research.
Document without altering
Photograph the signature, number, blind stamps, labels and verso. Do not erase, retrace, clean or add marks. If the print is stuck to backing or sealed in a frame, ask a paper conservator or experienced framer before removal.
