Another image found under Picasso masterpiece

Pablo Picasso painted one of his masterpieces atop a work of art by an unknown Spanish artist, researchers at the Northwestern University/Art Institute of Chicago Center for Scientific Studies in the Arts, the Art Gallery of Ontario and the National Gallery of Art have found.

Using advanced imaging technology, the researchers found another painting under Picasso's La Miséreuse accroupie (The Crouching Woman), a work from 1902, during the artist's "Blue Period."

Picasso not only changed the subject of the previous painting, from a landscape to a portrait, he also changed its direction, from horizontal to vertical.

The discovery of the artwork hidden beneath the surface allows us "to look inside Picasso's head and get a sense of how he was making decisions as he was painting the canvas," says Marc Walton, a cultural heritage scientist at Northwestern.

The findings were announced at the annual meeting of the American Association for the Advancement of Science in Austin.
