World War II posters helped mobilize a nation. Inexpensive, accessible, and ever-present, the poster was an ideal agent for making war aims the personal mission of every citizen, calling upon every American to boost production at work and at home. With growing concerns from the American public about the use of propaganda on the home front, the Office of War Information (OWI) helped control the content and imagery of war messages by using more positive imagery that involved citizens and personalized the war effort. United We Will Win: WWII Posters that Mobilized a Nation showcases the Historical Museum at Fort Missoula’s collection of over 650 original WWII posters.
