Firstly, I want to apologize for grammatical and spelling mistakes because I am from Germany and therefore my English isn't the best. My history teacher is clueless who that man on the bottom right could be. I figured out it would be a good idea to ask Reddit since the whole Community solved many cases that seemed impossible to solve. Anyways, my guess would be Kurt von Schleicher but I'm not entirely sure. Thanks for any help! Link: https://imgur.com/a/W4peZ
