This handwritten envelope, mailed by PFC R. Moon to a correspondent in Richmond, California, illustrates the vital role of the postal system in connecting American servicemen with loved ones during World War II. Routed through the San Francisco Army Post Office to APO 466 in the Pacific Theater, and bearing a wartime 6-cent Air Mail stamp, this letter is one of many personal exchanges that sustained morale across the vast distances of the Pacific war.
