In 2010, historian Gerd Krumeich, a German expert on the First World War, came to the conclusion that Hoffmann had doctored the image. Krumeich examined other images of the rally and was unable to find Hitler in the place where Hoffmann's photograph placed him. Also, in a different version of Hoffmann's photo in the Bavarian State Archive, Hitler looks different than in the published image. As a result of the doubt raised by those considerations, the curators of a 2010 Berlin exhibition about the Hitler cult inserted a notice saying that the image's authenticity could not be vouched for.
