Georgiana Adams writes about the bitter battle over the Victor Vasarely (1906–1997) estate. Prices for his pioneering op-art compositions are re-heating as is the complex story about ownership issues.

Also, Adams notes that German auctioneer Robert Ketterer is trying to raise money for a Bavarian town to buy Blaue Reiter artist Heinrich Campendonk's estate to show in a museum. In the meantime, dealers are lining up to buy the works.
