Metamorphosis of a painting

The National Gallery of Art explores Pablo Picasso's "blue period" masterwork, "The Tragedy," which was painted over earlier works. Using tools of the curatorial trade, such as infrared reflectography, the National Gallery exposes what lies beneath the surface painting of the forlorn family. Includes an animation and a video that reveal parts of four other works of art previously composed by Picasso before the final painting.
