This official Philadelphia '76 Commission First Day Cover honors INTERPHIL '76, the international philatelic exhibition held in Philadelphia. It bears the 13¢ Interphil commemorative stamp postmarked Philadelphia, PA on the first day of issue, January 17, 1976, with a striking cachet produced by the exhibition organizers.
INTERPHIL '76 celebrated the U.S. bicentennial and brought together collectors from around the world. The cachet highlights treasured American first day covers, prominently featuring the legendary $5 Freedom Issue of March 20, 1923—known as the world's most costly FDC—and references the famous 24¢ Inverted Jenny airmail stamp.
A notable detail is the reproduction of an early cover addressed to A. M. McFadden in Mount Rainier, Maryland, underscoring the exhibition's focus on postal history. The design also includes the Liberty Bell '76 logo and the exhibition dates of May 29–June 6, 1976.
This cover makes an excellent addition to any U.S. stamp or exhibition topical collection, with clean condition and strong visual appeal for display.
