A Picasso and a Mondrian painting disappeared almost 10 years ago in a museum heist. Greek police just found them.

Stolen paintings by artists Pablo Picasso and Piet Mondrian have been recovered by Greek police, who have arrested a man in connection with a museum heist that took place nearly a decade ago. 

In 2012, thieves broke into Greece's National Gallery in Athens and nabbed Picasso's 1939 painting "Woman's Head" and Mondrian's 1905 "Mill." The former was personally donated by the Spanish artist in recognition of Greece's resistance against the Nazi occupation during World War II.  That artwork is particularly special. The back of the painting features the inscription: "For the Greek people, a tribute by Picasso."
