World War I required the marshalling of the resources of the United States as never before. Industries that were geared to the production of automobiles, sewing machines, etc., were shifted to the production of war materiel such as guns as well as new weapons such as airplanes, warships, and submarines.
There were also massive efforts to recycle materials, to get people to invest in the war effort through the buying of war bonds. Children were encouraged to participate by helping to collect the recyclables and to buy stamps with their nickels, dimes, and quarters.
Because most of the male workforce was in uniform and deployed overseas to fight, women worked in factories in greater numbers than ever and took jobs that had been held by men. The whole country was encouraged to be part of the overall effort to help win the war. Posters like this encouraged all Americans to support the war effort.
