In 1998, it was discovered that the Galerie Belvedere had several works stolen from Jewish owners during the war. One of Ferdinand's nieces, Maria Altmann, hired a lawyer and made a claim against the gallery for the return of five works by Klimt. After a seven-year legal battle, an arbitration committee agreed that the painting had been stolen and should be returned to Altmann. She sold it in 2006 for $135 million.
