by Egon Schiele, 1916. Sometimes called Schiele's greatest painting, this work was stolen from its Jewish owners by Nazi police in 1938 and subsequently sold, and it ended up in a museum in Linz, Austria. It remained there for several decades until the movement to restore art stolen by the Nazis became widespread, and the museum finally relented and returned the painting. The heirs of the original owner sold the painting at auction in 2003 for $12.6 million.
