3. Eduardo de Valfierno
Eduardo Valfierno was an Argentinean scammer who stole the Mona Lisa and paid a skilled art forger to make copies of the masterpiece. Valfierno paid Vincenzo Peruggio, an employee of the Louvre Museum, to steal the Mona Lisa. He didn’t intend to sell the original painting and only wanted to make it disappear so buyers who bought a copy would believe that they had the original. Peruggio was caught trying to steal the original painting and denied that he knew Valfierno.
