Alberto Giacometti was one of the great artists of the 20th century. Although he took the art of self-effacement to extremes, he is paradoxically the sculptor whose work sells for the highest prices worldwide. He is also among the most copied. This came to light when the Lothar Senke affair broke. Senke was a German art dealer who coordinated a vast scam trafficking forged Giacometti sculptures. For more than ten years, he dealt in thousands of works faked by Robert Driessen, a Dutch counterfeiter who closely copied Giacometti’s style and techniques.
