Hello! I've just bought this old portrait and I am very curious about it. I want to find out more about it and maybe someone here can help. I wonder who this man is and who the artist was. The signature doesn't help too much, I can't really read the name. Can someone recognise something and tell me more about it? I think it's an old portrait made in german POW camps and I also sense something gay about it, maybe a hidden story or something. I know it's a very basic portrait but I like it so much, there's something I feel attracted to. And I really want to find out its story. 1945 is written on it so there are chances some people from their life could be still alive. I'm curious about your thoughts.
