Experts analyzing the painting have several theories about why this unidentified woman has remained submerged for more than a century.

Conservators at the Courtauld Institute of Art in London revealed a hidden portrait beneath Pablo Picasso's 1901 painting "Portrait of Mateu Fernández de Soto," adding a new layer of complexity to one of the artist's Blue Period iconic works.

Nearly 125 years after Pablo Picasso painted one portrait, high-tech imaging tools have revealed a secret — another, earlier portrait concealed beneath.

Art historians studying a Picasso painting uncovered the mysterious portrait of a woman hidden beneath the painting’s surface. The portrait of the woman was lost in 1901, when Picasso painted a portrait of his sculptor friend Mateu Fernández De Soto over the original.
