To control the form of war messages, the government created the U.S. Office of War Information in June 1942. OWI sought to review and approve the design and distribution of government posters. Posters such as this one and their messages were seen as "war graphics," combining the sophisticated style of contemporary graphic design with the promotion of war aims. Over time, OWI developed six war-information themes for its own internal use, as well as to guide other issuing agencies and major producers of mass-media entertainment.
