Mona Lisa v2.0

A copy of Leonardo da Vinci’s Mona Lisa that was painted at the same time as the original in the same studio is displayed at the Prado Museum in Madrid. The museum says the copy it has is the earliest replica of the masterpiece. A museum spokeswoman said the work was painted side by side with the 16th century original that hangs in the Louvre in Paris and was done by one of Leonardo’s key students.
