Author: Matthias Engelhardt, as a successor of Ilse Reicke Source: It is partially my work - the photo is taken form the inheritance of Ilse Reicke, and I have scanned it. On the back, it is written that the photo was taken by Maria Valtingojer in Bad Pyrmont, Germany, around 1950. I strongly assume that Ilse Reicke had paid for the photo and thereby got all rights.
