Helene Plotkin's son turned to Google Gemini when curiosity struck about a painting she bought for under $100 at a White Plains thrift store in 1966. The AI assistant quickly identified distinctive characteristics pointing to Scottish Colorist F.C.B. Cadell, including Art Deco aesthetics and signature color palettes that matched the artist's known work.

Gemini directed the family to check the painting's back, where they found auction markings and a canvas stamp. The AI recommended contacting specialists at Lyon & Turnbull, who confirmed the work was indeed an original studio portrait from the 1920s. Technical analysis under multiple light sources verified the painting's authenticity, though the model's identity differed slightly from Gemini's initial assessment.

The authenticated Cadell sold at auction this month for £189,200 with fees, approximately $254,000, demonstrating how artificial intelligence tools can democratize art authentication services. This case shows AI potentially disrupting traditional appraisal workflows, allowing ordinary people to identify valuable works that might otherwise remain unrecognized.

Plotkin, 88, plans to let her sons handle the proceeds, hoping the private buyer might display the piece publicly. The sale underscores how technology is reshaping expertise-based industries, with AI serving as a gateway to professional services rather than replacing them entirely.
