Made from 100% SolarGuard Nylon, America's No. 1 choice for Flags. Heading is sturdy duck with strong brass grommets. Durable and fast-drying, the dyed design conforms to official state specifications. Available in five sizes. The Oklahoma state Flag was designed by Luise Fluke and Dr. Joseph Thoburn and adopted in 1925 for a Daughters of the American Revolution competition. The name of the state was added in 1941. The design consists of an Osage war shield crossed by an olive branch and a peace pipe on a light blue field. The blue was derived from the Flag the Choctaw flew during the Civil War.
