A bloody hand print over the text exhorts Americans to “blot out” the Hun by supporting Liberty Bonds. The term Hun was a derogatory nickname used in WWI by British and American officers to describe the German army. Its origin comes from Kaiser Wilhelm II’s instructions to his troops during the Boxer Rebellion to behave like the Huns of old and wreak vengeance. Allied propaganda used the term to suggest the worst kind of conduct from the Germans: crushing neutral nations and imposing brutal rule upon conquered people. This was the first poster to use the term.
