Inside the Matthiesen Gallery Lawsuit: Art Fraud, Gustave Courbet’s Masterpiece, and Legal Battles in the Old Masters Market
Share
The Matthiesen Gallery, a prestigious London-based dealer specializing in Old Master paintings, has taken legal action that is sending ripples through the art world. In a complex lawsuit filed in the Southern District of New York, the gallery accuses a web of individuals—including convicted con man Thomas Austin Doyle, the Jill Newhouse Gallery in New York, prominent art collector Jon Landau, and artist-dealer Shalva Sarukhanishvili—of orchestrating a multi-year fraud scheme involving a notable Gustave Courbet painting, Mother and Child on a Hammock.

Background of the Dispute: Art Sales and Alleged Deceptions
The lawsuit centers on the provenance, pricing, and transfer of the Courbet painting. According to court documents, Doyle misled Patrick Matthiesen, managing director of the Matthiesen Gallery, by presenting a buyer willing to pay $550,000 without commission—a significantly lower figure than the painting’s established value of $650,000, a price publicly maintained for years and verified at major art fairs such as TEFAF New York 2019.
Doyle allegedly transferred the painting to Shalva Sarukhanishvili, who then sold it to the Jill Newhouse Gallery, which subsequently sold it to Jon Landau, a collector listed among the ARTnews Top 200 collectors, for $1,125,000 in 2023. Matthiesen claims the defendants breached contractual obligations and engaged in fraudulent activities by undervaluing and mishandling the transaction, refusing to return the artwork or the funds owed despite legal requests ArtNews lawsuit coverage.
