History of loss: Museum of Cultural History, Osnabrück, 1945/1946. The paintings were stolen between 1945 and 1946 from the museum, which had been partially damaged by bombing and misappropriated. The museum has no catalogues from the period before 1945, only a handwritten notebook in which the lost paintings are still described. (cf.: Verlorene Werke der Malerei 1965, p. 166)
