“Still’s widow in 2004 bequeathed her husband’s valuable collection to Denver with the understanding that a museum would be constructed to display the works. The proceeds of the sale of four paintings will go to fund an endowment that will pay for the museum’s operations. The museum’s collection will include 825 paintings, 1600 drawings and three sculptures. Both New York-based Sotheby’s and London-based Christie’s auction houses bid to sell the works. Sotheby’s won, outraging Christie’s and setting off a public dispute.”
