"The world cry, food--Keep the home garden going." A WWI propaganda poster for the home front designed for the United States Food Administration. Because so much food was needed for soldiers and starving civilians in Europe, Americans were encouraged to keep gardens. (In World War II, these gardens would be called “victory gardens.”) This poster shows three men with crops in poses like those in Archibald Willard’s famous painting Spirit of ‘76, and calls on the “Spirit of ‘18.”
