The market for American art isn’t exactly hot but Bill Koch thinks it is a good time to sell. Christie’s have just announced a $13m single-owner sale for late May:

Christie’s announces the sale Visions of the West: American Paintings from the William I. Koch Collection, which represents the breadth of Western Art with works spanning the 19th Century to the present day. The dedicated sale will take place on May 21, at noon, following Christie’s Spring sale of American Art, and will feature more than 65 paintings from Mr. Koch’s superb collection.
