The first government-issued stamp to depict an airplane was US Scott #Q8 in 1912. However, that is not the first stamp to depict an airplane. That distinction belongs to US Scott #CL2, an airpost semi-official stamp privately issued in 1991. It is known as Rodgers Aerial Post.
The first airplane on a stamp.
The first ‘government-issued’ stamp to depict was the 20-cent Parcel Post stamp (Scott US #Q8, figure 1.) issued by the United States on December 16, 1912. The stamp featured a biplane carrying mail and was part of a series parcel-post stamps that depicted various methods of mail transportation
The first ‘stamp’ in the world to depict an airplane was the Rodgers Aerial Post stamp (Scott US #CL1, figure 2), also known as the Vin Fiz Flyer stamp, issued in 1911. The stamp was privately issued to commemorate Calbraith Perry Rodgers first transcontinental flight in the Vin Fiz Flyer, a Wright Model EX biplane while competing for a $50,000 prize offered by William Randolph Hearst. Rodgers was sponsored by Armour meat-packing company who made a soft drink called Vin Fizz.
The stamp was privately issued by Rodgers’s wife in Texas around Oct. 19th, 1911. The stamp was used to frank mail carried on the flight, and only 13 examples are known to exist today making it a highly prized collectible among philatelists1
