Salvator Dali’s biographer claims that he owns the rights to Dali’s commercial work. But the Dali Foundation disputes the claim, and the row hangs like a cloud over celebrations of the surrealist’s 100th birthday. “Dalí has turned out to be as much of a cash generator since his death as he was during his money-obsessed career. The foundation, which runs a museum in his birthplace, Figueres in north-east Spain, expects to earn more than €1m a year.”
