Willi Graf moves to Mandl-Str. 1
To come back to my former room at Mandel Str. 1, I will add that when Graf returned from Russia, he was looking for a room. My brother made him aware that my former room at Mandel Str. 1 was available at that time, because the landlady actually did not intend to look for another boarder. Garf [sic] then got this room, where he resided till the end.
