Start With the Image Itself

The screenshot is your best evidence, so work it before anything else. Run it through Google Lens first, then TinEye if Lens returns nothing useful. Lens matches visually similar images across the web; TinEye finds exact duplicates, which matters if the page you saw was itself reposting someone else's photo. Between the two, one usually surfaces the original source, and the original source almost always carries a caption with the title and date.

Greene worked in two distinct modes, which helps narrow things down. His abstract paintings from the 1930s and 1940s look nothing like the figurative work of his later decades, so noting which camp your image belongs to will cut the search space considerably. If you can see a signature, transcribe exactly what it says, including any date. Collectors and databases index on those details, and a partial title beats no title. For context on what tends to circulate, the guide to Greene's most recognizable subjects is a useful cross-check Greene's most recognizable subjects.

Turn a Screenshot Into a Search

Once you have a candidate title, verify it rather than trusting the first page that uses it. Auction house listings and museum collection databases are the reliable anchors, because their captions come with dates, dimensions and medium. A print seller's page that lists only a title and a price, with no dimensions, is worth less. Cross-checking two independent sources takes ten minutes and prevents you from ordering a reproduction of a painting that turns out to be by someone else entirely.

This is the step where frustration sets in for most people, because image search returns lookalikes mixed in with the real thing. Filter ruthlessly. If the composition matches but the palette is off, keep looking. When you do land on the right work, decide what you actually want from it, since a framed poster on paper and a canvas print behave differently on a wall, a comparison covered in the guide to choosing between formats canvas print or framed poster. The same discipline applies to any edition you buy elsewhere, for instance a framed poster edition a framed poster edition will always list its paper type and dimensions plainly.

When the Search Comes Up Empty

Some Greene images circulate with no caption at all, lifted from books or auction archives and stripped of their labels. If reverse-image search fails after a few rounds, try searching the artist's name alongside descriptive terms instead. Composition words work well. Figures, harbor, interior, abstract shapes. His name is unusual enough that even a loose keyword combination rarely drowns in results, unlike searches for common surnames.

Accept that a minority of images will resist identification. If the work is an obscure or unrecorded piece, no amount of searching will produce a clean title, and no reproduction seller will carry it. In that case the honest options are narrower. You can save the image and keep looking periodically, since databases expand. Or you can choose a documented Greene work that resembles the one you saw, which is often the more satisfying outcome anyway, because a titled, dated work carries a provenance you can actually read. The overview of Greene's subjects what Greene painted most will point you toward the better-documented territory.
