Scientists use AI, X-rays, and 3D printing to reveal a hidden Picasso

The Blind Man’s Meal is among the most important artworks of Pablo Picasso’s Blue Period, but it also shares a canvas with a more mysterious painting.

Underneath the oil paint lies a portrait of a naked woman in the shape of a heart. Picasso had painted over the picture, which wasn’t unusual for the artist when money was tight.

The painting had been concealed since 1903, but a combination of AI, stereoscopic imaging, and 3D printing has peeled back the cover.
