World War II posters helped to mobilize a nation. Inexpensive, accessible, and ever-present, the poster was an ideal agent for making war aims the personal mission of every citizen. Government agencies, businesses, and private organizations issued an array of poster images linking the military front with the home front–calling upon every American to boost production at work and at home. Deriving their appearance from the fine and commercial arts, posters conveyed more than simple slogans. Posters expressed the needs and goals of the people who created them.
