For the most part, the Contemporary art sales held in Milan at Sotheby's and Christie's as the end of April and beginning of May featured strong performances by the stalwarts of Italian Contemporary art, Lucio Fontana, Enrico Castellani, Alighiero Boetti, Alberto Burri, and Giorgio Morandi. But the big stars of the sales were two works by Josef Albers that sold well above their estimates at Sotheby's.
