The restitution of the drawings of Egon Schiele (1890-1918) represents an important victory for the heirs of Fritz Grünbaum. The Austrian Jewish artist and collector was deported to the Dachau concentration camp, where he died in 1941. His wife, Elisabeth, was then forced to hand over the entire collection to the Nazi authorities, before being deported and killed at the Maly Trostinec concentration camp. The works had reappeared on the art market in the 1950s, first in Switzerland, then resold on the New York square.
