Is the Mona Lisa hanging in Paris/Louvre the real one? There are "other versions" and copies that are well known. It was stolen in 1911 after all, as well as vandalized a couple of times. There have been several people who have had occasion to ask if the Louvre is displaying the real painting (whether for protection or that a thief made off with the original).
