Patriotic post office road sign

c. 1940 - 1965

In addition to serving as recruitment and draft registration centers, local post offices have contributed to boosting wartime morale through such efforts as blood donor drives, war bond sales, and letter campaigns for service men and women. The York, Pennsylvania, post office supported the U.S. Marine Corps with this patriotic road sign. Although very little is known about the circumstances behind this sign, the listing of a five-digit phone number dates the sign to the mid- twentieth century, around the time of America’s involvement in the Korean War.
