US Air Mail (Red)

WASHINGTON — The U.S. Postal Service is issuing a second Forever stamp this year to commemorate the 100th anniversary of U.S. airmail service.

United States Air Mail Red commemorates the centennial of an Aug. 12, 1918, flight from College Park Airfield in Maryland to New York City that became the first step in establishing transcontinental air routes. The first stamp, United States Air Mail Blue, paid tribute to the pioneering spirit of Army pilots who initiated service in May of the same year.
