Three artworks by Austrian Expressionist Egon Schiele, previously owned by Fritz Grünbaum, were seized by New York law enforcement authorities as part of a joint investigation. The artworks were taken from the Art Institute of Chicago, the Carnegie Museums of Pittsburgh and the Allen Memorial Art Museum at Oberlin College in Ohio. The seizure is part of a larger effort to return stolen art to its rightful owners and to investigate and prosecute those responsible for the theft of art during the Holocaust.
