This Official First Day Cover features the 25¢ US Airmail stamp issued January 2, 1976, in Honolulu, Hawaii. The stamp depicts a modern jet airliner against a red, white, and blue design with globe motifs, part of the "Vignettes of Americana" series released for the new postage rates.
The cover commemorates the history of international airmail. Its cachet illustrates the Boeing B-1 biplane used by Seattle aviator Edward Hubbard, who inaugurated the first international airmail route in 1919 between Seattle and Vancouver.
A notable detail is the dual-era artwork: the cachet celebrates early aviation pioneers while the stamp represents contemporary jet-age airmail service. The Honolulu postmark ties the cover to a key Pacific gateway for airmail routes.
This well-preserved FDC is an appealing addition for collectors of airmail, aviation topicals, or 1970s US postal history, with strong display value and clear historical context.
