This Official First Day Cover features the 13¢ Idaho state flag stamp from the Bicentennial Era series, postmarked in Washington, DC on February 23, 1976. The cachet honors William Edgar Borah with a striking illustration of his statue alongside the Idaho flag.
Borah served as a U.S. Senator from Idaho for over three decades, earning the nickname "The Lone Lion of Idaho" for his independent stance on foreign policy and progressive domestic views. Idaho had joined the Union as the 43rd state in 1890, just five years before Borah arrived in the territory.
The cachet artwork includes Borah's life dates (1865-1940), his roles as lawyer, legislator, and statesman, and the text noting Idaho's admission to the Union. The stamp itself belongs to the popular 50-state flags series issued during the American Bicentennial.
A fine addition for collectors of state flag issues, political figures, or Idaho postal history, this cover remains in excellent condition with a crisp first-day cancel.
