The United States joined the First World War in April, 1917. Learning from the British, the United States put its propaganda efforts into the hands of one organization, the Committee on Public Information, also called the Creel Committee, after its chairman, George Creel.
The Creel Committee produced a few features. The first was Pershing's Crusaders. "Pershing's Crusaders was taken by the U.S. Signal Corps and Navy Photographers and the French General Staff."
