This is a very large official photo (the size of almost a poster!) of Foreign Minister of nazi Germany and SS-Obergruppenführer Joachim von Ribbentrop.
The photo measures 40 x 30 centimeters and shows what appears to be an early 1930’s photo of von Ribbentrop wearing only a NSDAP partybadge on his tie.
Of all pictures of von Ribbentrop this is one of his most “intense” looking photo’s and it clearly shows that he was a terrible person. In my opinion it very well shows why his nickname during the 1930’s and during the war was “von Ribbensnob”.

The name of the photographer “Röhn” is in the lower right corner.
A rare photo in a very rare large size!
