United States Airmail Stamp C3 'Jenny'

United States · 1918 · 24c

This iconic stamp features a blue vignette of a Curtiss JN-4 'Jenny' biplane, framed in carmine rose. It was the first airmail stamp issued by the United States, created to prepay the rate for the new airmail service between Washington D.C., Philadelphia, and New York City.

Issued in 1918, this stamp marks the beginning of regular airmail service in the United States, a significant milestone in postal history and aviation. A famous error version, the 'Inverted Jenny', where the plane is printed upside down, is one of the most valuable rarities in all of philately.
