This First Day Cover features the 13¢ Colorado centennial stamp issued May 21, 1977, and postmarked in Denver, Colorado on the official first day of issue. The cachet, beautifully illustrated by Charles Berger, shows the Lark Bunting perched among Rocky Mountain Columbines—the state's official bird and flower.
Colorado entered the Union on August 1, 1876, earning the nickname "Centennial State." The stamp's design highlights the columbine blossom against a mountain backdrop, celebrating both the state's natural beauty and its 100th anniversary of statehood.
A notable detail is the coordinated artwork pairing the two state symbols on the cachet, a popular approach for collectors of state flora and fauna topicals. The cover carries the clear "FIRST DAY OF ISSUE" handstamp and the distinctive Denver postmark.
A fine example for statehood, bird, or flower topical collections, this cover displays fresh colors and sharp postmarks, making it an attractive display piece or gift for the philatelist.
