Walter explains: "I don’t know the name of the man in this picture, but he was hiding in Berlin, and we met at the opera. I went there sometimes to sit down and rest. He gave me the photo as he wanted to leave something that he could be remembered by if he wouldn’t survive. One day when we had decided to meet, and I was watching out the window. The man came along, and I noticed that two Gestapo men were in his heals. They arrested him, and I never saw him again."
