Art Recognition’s algorithm is trained to identify specific artists’ patterns of style and composition. Art enthusiasts can find works by celebrated artists such as Vincent van Gogh, Salvador Dalí, and Henri Matisse on eBay, a platform that has become a marketplace for high-value art pieces. One notable listing is “Forest With a Stream,” which is available for $599,000. This piece exemplifies how eBay offers a unique opportunity for collectors to acquire prestigious artworks from around the globe.

A listing on eBay advertises an original antique French Impressionist oil-on-canvas painting by Claude Monet, titled “Forest With a Stream,” priced at $599,000. The listing claims the piece is signed “C. Monet” and dated 1867. However, Carina Popovici, CEO and co-founder of Art Recognition, a company specializing in the use of artificial intelligence for art authentication, has raised doubts about the painting’s authenticity.

Popovici explained to the Guardian’s Dalya Alberge that Art Recognition’s AI technology analyzed images of various paintings listed on eBay and identified many as likely forgeries. Among the flagged items is the “Forest With a Stream” painting, as well as a $165,000 work attributed to Pierre-Auguste Renoir. According to Popovici, their algorithm has identified 40 paintings on eBay as potentially inauthentic, underscoring the challenges of verifying the authenticity of high-value artworks sold online.
