This First Day Cover features the 13¢ Delaware state flag stamp, issued as part of the Bicentennial Era series. The cover is postmarked Washington, DC on February 23, 1976, the official first day of issue, with a crisp black circular cancel.
Delaware holds a special place in American history as the first state to ratify the U.S. Constitution on December 7, 1787. The stamp's design incorporates the state flag with its distinctive blue, buff, and orange diamond motif, along with the date of that historic ratification.
The cachet artwork depicts the Delaware State House in Dover, the Great Seal of the State of Delaware, and the nickname "The Diamond State," tying the visual elements directly to the stamp's theme.
A strong addition for collectors of state flags, U.S. bicentennial issues, or Delaware postal history, this cover remains in excellent condition with sharp graphics and a clear postmark.
