Entitled: "Clear-the-way!! Buy bonds - Fourth liberty loan". Poster shows a woman symbolizing America above naval gun crew in action. A Liberty Bond was a war bond that was sold in the United States to support the allied cause in World War I. Subscribing to the bonds became a symbol of patriotic duty in the United States and introduced the idea of financial securities to many citizens for the first time. The Act of Congress which authorized the Liberty Bonds is still used today as the authority under which all U.S. Treasury bonds are issued. Through the selling of Liberty bonds, the government raised around $17 billion for the war effort. Considering that there were approximately 100 million Americans during that time, each American, on average, raised $170 on Liberty bonds. Artist Howard Chandler Christy, 1918.
