Issued in 1978 by the United States Postal Service, this bright orange-red “A” rate stamp features a stylized eagle in flight, symbolizing speed and reliability in mail delivery. The large letter “A” indicated the first-class postage rate of the time (15¢) without showing a numerical denomination, introduced to facilitate quick rate changes. Part of the 1978–1981 alphabet series, this design marked a transition toward modern, simplified postal graphics. A notable collectible for both U.S. definitive stamp enthusiasts and thematic bird collectors.
