1977 - 11 Cents USA Air Mail Red Scott C78

11 Cents USA Air Mail Red is a postage stamp issued by the United States Postal Service (USPS) for use in sending letters and packages through airmail services. The stamp has a face value of 11 cents, which was the standard postage rate for airmail letters weighing up to one ounce at the time of its release.

The design of the stamp features a vibrant red background with the words "U.S. AIR MAIL" in white letters. In the center of the stamp is an image of a biplane, which was a common type of aircraft used for airmail delivery in the early 20th century. The biplane is depicted flying over a stylized map of the United States, with lines radiating out from its location to signify the routes flown by airmail planes.

The 11 Cents USA Air Mail Red stamp was first issued on August 1, 1977, and was in use until the postal rate for airmail letters changed in 1981. It was printed in a large quantity, so it is still relatively easy to find in unused condition today. Stamp collectors and enthusiasts may be interested in adding this stamp to their collections as a representation of the history of airmail and the United States Postal Service.
