Just a guess that’s probably wrong, but my first thought is Rommel.
Isn’t that Field Marshal Montgomery?
Nothing like him.
Perhaps Sepp Dietrich, but I’d expect to see a death’s head cap badge instead of the roundel shown in the OP photo.
Same nose.
t doesn’t look like any German uniform I’ve ever seen, and there’s no insignia to indicate nationality. Maybe Spanish or Italian?
Yes - little-known fact; they shared it via neutral Swiss courier. As an on-going practical joke, they’d compete to see who could return it stuffed with the most objectionable matter.
After looking it up, I’m 98% sure it’s not Rommel. I was going by the cap of the dude standing in the background.
That is not Montgomery. He is not wearing a British uniform. Of course he could be at a fancy dress party.
Turns out it was this fellow: Hasso von Manteuffel - Wikipedia
Indeed you are correct, as verifiable at this site.
The guy in the background, what is the emblem on his cap? Looks like an X but doesn’t appear to be a swastika.
