An Austrian Jewish entertainer’s heirs, who recently won the rights to two Egon Schiele paintings looted by the Nazis in the 1930s, are asking a New York judge to transfer the paintings to Christie’s auction house so that they can sell them in conjunction with the 100th anniversary of Schiele’s death.

But Richard Nagy and Richard Nagy Ltd., the replevin and conveyance case defendants—who still have possession of the paintings—are opposing the motion.
