Raubkunst
In 1935 the painting "Die Labung" had been stolen by the Nazi regime. In 1980 it came into the possession of the Museum Wiesbaden. In order to fulfill the museum's project of identifying Nazi plunder and to return it to the legitimate heirs - the museum kept showing only the backside of the work, until they collected enough money through donations to buy it at the end of the same year.
