Match the crop to the task
For the artwork's source, remove the frame from the search copy. For the framed item as sold, keep it. Do not crop away a signature or publisher's mark that could provide attribution.
Compare deliberately
- Search the full framed item.
- Search the image-only crop.
- Read source descriptions and product identifiers.
- Record whether you found the artwork or the exact framed product.
A familiar print can be sold in many frames. Finding the image does not establish the maker or value of the surrounding frame, and matching a frame style does not identify the print's creator.
Avoid perspective inventions
A simple straightening correction may help a phone photograph of a print. Keep that edited copy separate and do not generate missing corners. If detail is insufficient, obtain a better permitted photograph rather than treating a visually similar wall-art listing as an exact source.
