Professor Alessandro Vezzosi, director of the “Museo Ideale Leonardo da Vinci,” speaks in Geneva about a painting attributed to Leonardo da Vinci representing the Mona Lisa. The Mona Lisa Foundation, a non-profit organization based in Zurich, presented a painting and historical, comparative and scientific evidence to demonstrate that there have always been two portraits of the Mona Lisa by da Vinci, one being the ‘Earlier Version,’ made ten years before the ‘Joconde’ that is displayed in the Louvre in Paris.
