Issued on February 23, 1976, as part of a pane of 50 stamps celebrating the flags of all 50 states during the nation's bicentennial, this stamp features the Oklahoma state flag. The flag itself is a beautiful and meaningful representation of the state's history. The blue field is inspired by a flag carried by Choctaw soldiers during the Civil War. The central image is an Osage warrior's buffalo-hide shield, adorned with eagle feathers. Across the shield are two symbols of peace: a peace pipe, representing Native Americans, and an olive branch, representing people of European descent. The small crosses on the shield are Native American symbols for stars, signifying high ideals. The word "OKLAHOMA" was added to the flag in 1941. This stamp serves as a philatelic tribute to the state's rich cultural tapestry and its message of peace and unity.
