And actually, isn't that picture of Hitler a composite image? Hence Kurt's line, "Just kidding". The figures look like they've been photo-shopped onto the Hitler photo, and actually, they look like larger, ceramic figures, than metal or composite.
Though there was a collection of figures that had belonged to the Hohenzollerns, and was stored at one of the palaces, maybe Charlottenburg, that were larger (12", perhaps), cast in Britannia metal and painted. I've seen pictures in one of the older toy soldier books, and they were very life-like in their detail. They were destroyed during the air raids on Berlin.
Any figures that the "Greatest Commander of all time" (Größter Feldherr aller Zeit or Gröfaz, as they used to say) were probably gifts from the makers, to curry favor or also draw prestige to their respective firms.
Prost!
