In this artwork, how is the Ownership history discussed?
De Kooning sold the painting in the Sidney Janis Gallery shortly after it was completed for $4,000 to architect Edgar Kaufmann Jr., whose father Edgar J. Kaufmann owned Kaufmann's department store in Pittsburgh.  Kauffman's estate sold the painting, alongside other pieces of his art collection, at Sotheby's in New York in November 1989, during the Japanese asset price bubble, to Japanese art dealer Shigeki Kameyama, owner of the Mountain Tortoise Gallery in Tokyo, for $20.7 million, setting a then-record price for a living artist. The sale occurred 3 months after a judge declared de Kooning to be mentally incompetent due to Alzheimer's disease.The painting was sold a few years later to David Geffen, at a loss due to the bursting of the Japanese asset price bubble and the early 1990s recession.In September 2015, Geffen sold Interchange for $300 million to hedge fund manager and billionaire Kenneth C. Griffin. Griffin paid $500 million for two artworks, including $200 million for Jackson Pollock's Number 17A.
