This First Day Cover features the 13¢ Colorado stamp issued May 21, 1977, in Denver, Colorado. The stamp depicts the Rocky Mountains and the state flower, the Rocky Mountain columbine, with the inscription “THE CENTENNIAL STATE.”
Colorado entered the Union on August 1, 1876, exactly one hundred years after the Declaration of Independence, earning its nickname as the Centennial State. The 1977 stamp commemorates that milestone and highlights the state’s iconic alpine scenery.
The cover carries a crisp “FIRST DAY OF ISSUE” hand-cancel from Denver (ZIP 80202) and is addressed to collector John W. Terkats in Philadelphia, Pennsylvania—an interesting cross-country journey for a Western-state topical.
A clean, attractive addition for collectors of U.S. state issues, Colorado topicals, or 1970s First Day Covers.
