This First Day Cover bears the 13¢ Continental Soldier stamp issued for the American Bicentennial, cancelled with the official May 29, 1976 Philadelphia, PA postmark during INTERPHIL '76.
The stamp depicts a Revolutionary War soldier in full uniform and commemorates the Continental Army's pivotal role in securing American independence two centuries earlier.
The cachet was produced for the 21st Annual Convention of the American First Day Cover Society, with the red society logo and convention text prominently displayed at the bottom.
A strong addition to any Bicentennial, military, or FDC topical collection, the cover remains in clean, collectible condition with sharp postmark and vivid cachet artwork.
