Hoffmann's photographs were a significant part of Hitler's propaganda campaign to present himself and the Nazi Party as a significant mass phenomenon. In 1926, Hoffmann's images of the Party's rally in Weimar in Thuringia – one of the few German states in which Hitler was not banned from speaking at the time – showed the impressive march-past of 5,000 stormtroopers, saluted by Hitler for the first time with the straight-armed "Roman" or Fascist salute. Those pictures were printed in the main Nazi newspaper, the "Völkischer Beobachter", and distributed by the thousands throughout Germany. That rally was the progenitor of the Party's annual mass rallies, which were staged quasi-annually in Nuremberg. Later, Hoffmann's book, "The Hitler Nobody Knows" (1933) was an important part of Hitler's strenuous effort to manipulate and control his public image.
