Portrait of Adele Bloch-Bauer I
Maria Altmann was a member of a wealthy Jewish family whose possessions were confiscated by the Germans. The famous painting by Gustav Klimt was of her aunt.
After the war the state of Austria took possession of the Klimt paintings, and over time the Austrians took them to be part of the Austrian culture.
The ownership was settled in Austria by arbitration. Maria Altmann took possession of five paintings and shortly afterwards sold them for $327 million. The picture of her aunt is now in the Neue Galerie, New York
