Christie’s will auction the remaining four Gustav Klimt paintings returned earlier this year after being looted by Nazis in World War II. “The four works, which are together valued at nearly $100 million, include ‘Adele Bloch-Bauer II,’ a 1912 portrait of Mrs. Bloch-Bauer in fashionable street clothes and a wide-brimmed hat. Christie’s estimates that it could fetch $40 million to $60 million.”
