Oklahoma

The state has carried various unofficial designs during its history, with the current flag only getting official recognition in 2006. Based off of a 1925 design by Daughters of the American Revolution (them again), the ‘OKLAHOMA’ was added in 1941 to combat illiteracy.

The Osage Nation buffalo-skin shield is covered by two symbols of peace; the olive branch for European Americans and the Plains-style ceremonial pipe for Native Americans. The blue references the battle flag carried by the Chowtaw during the American Civil War.
