$158,500,000 for Gustav Klimt’s Portrait of Adele Bloch-Bauer I, 1907.

It took Gustav Klimt three years to complete this portrait of his wealthy friend and patron, Adele Bloch-Bauer. After the Nazis annexed Austria in 1938, the painting traded several hands until it was finally returned to Bloch-Bauer’s heir in 2006. Today, the painting is on display at the Neue Galerie in New York City.
