Thieves using a crow bar and hydraulic jack to break into the Sao Paulo Museum of Art in December, 2007, stole Picasso’s “Portrait of Suzanne Bloch” and Portinari’s “O Lavrador de Cafe.” They later called the museum’s president, demanding $5 million for the paintings’ return. No ransom was paid, but the paintings were found three weeks later in perfect condition.
