Does everyone have a doppelganger? Is this carved marble head that was the corner of a sarcophagus in Roman times proof that Elvis had a previous life? Some think Elvis is still alive today. The puzzling carving will sell at Bonhams in London on October 15, part of a $2 million sale of antiquities. Next thing you know, they may find the Latin words and music to his Roman hit songs, "Sandallium Caeruleum Alutum" (Blue Suede Shoes) and "Atroci No Existiti" (Don't Be Cruel).
