This Art Craft First Day Cover features the 21¢ United States Air Mail stamp issued May 21, 1971, in Washington, DC. The cachet commemorates the first air express shipment, flown November 7, 1910, in a Wright biplane by Phillip O. Parmalee from Dayton to Columbus, Ohio.
The 1971 Air Mail series marked a new era for U.S. postal aviation, highlighting the rapid growth of airmail service that began with experimental flights in the early 20th century. The stamp's bold red-white-and-blue USA design with a jet silhouette reflects the transition from biplanes to modern jet aircraft.
A notable detail is the detailed inset photograph of Parmalee in the Wright Flyer alongside a line drawing of the biplane, tying the 1971 issue directly to the 1910 milestone event. The cover bears the clear Washington, DC first-day postmark.
A fine addition for collectors of U.S. airmail, aviation topicals, or Art Craft cachets, this well-preserved FDC displays strong visual appeal and solid postal history interest.
