The Prado Mona Lisa is a painting by the workshop of Leonardo da Vinci and depicts the same subject and composition as Leonardo's better known Mona Lisa at the Louvre, Paris. The Prado Mona Lisa has been in the collection of the Museo del Prado in Madrid, Spain since 1819, but was considered for decades a relatively unimportant copy. Following its restoration in 2012, however, the Prado's Mona Lisa has come to be understood as the earliest known studio copy of Leonardo's masterpiece.
