Paul Durand-Ruel
Around 1884 Degas made a portrait in oils of Cassatt, "Mary Cassatt Seated, Holding Cards". Stephanie Strasnick suggests that the cards are probably "cartes de visite", used by artists and dealers at the time to document their work. Cassatt thought it represented her as "a repugnant person" and later sold it, writing to her dealer Paul Durand-Ruel in 1912 or 1913 that "I would not want it known that I posed for it."
