“The Blue Room,” one of Pablo Picasso’s first masterpieces at The Phillips Collection, on Tuesday, June 10, 2014, in Washington. Scientists and art experts have found a hidden painting beneath the painting. Advances in infrared imagery reveal a bow-tied man with his face resting on his hand, with three rings on his fingers. Now the question that conservators at The Phillips Collection in Washington hope to answer is simply: Who is he? It’s a mystery that’s fueling new research about the 1901 painting created early in Picasso’s career while he was working in Paris at the start of his distinctive blue period of melancholy subjects.
