The Prado museum's Mona Lisa [seen exhibited here at the Louvre's 'La Sainte Anne' exhibition in 2012]. Pause it at 0:20 to get a longer view [the clip is short & wobbly cuz it was a camera-unfriendly exhibition]. At the end [0:27] is Leonardo da Vinci's Mona Lisa masterpiece for comparison, which is permanently in the Louvre.
