An incredible discovery is making waves in the art world.
Researchers have discovered a painting by Pablo Picasso hidden beneath one of his most-famous works.
Using special infra-red camera technology, experts at the Phillips Collection in Washington uncovered a portrait of a bearded man in “The Blue Room.”
You can see the man wearing a jacket and bow tie. He has three rings on his fingers.
Now art historians are hoping they can identify the mysterious man in the painting.
It's long been known there was something hidden under the outer layers of "The Blue Room," but the technology to see it clearly only became available recently.
