The Mona Lisa
Ever heard of it? The answer is most likely yes, considering it is the most famous painting in the world. The criminal, Vincenzo Perugia, was a handyman working at the Louvre, where the painting is displayed. In 1911, he hid in a closet until the museum closed and then took off with it with two other handymen. It was finally recovered and returned to the Louvre in 1913 after Perugia attempted to sell it to an art dealer in Italy. This painting tops the list of the most expensive things ever stolen with a price tag of at least $2 billion.
