All State flags in our US State flag collection, including this 4' x 6'' Indoor Oklahoma State Flag, are made to official State design specifications. NYL-GLO Nylon Flannel Lined Pole Sleeve with Velcro Tabs Golden Yellow Rayon Fringe Not intended for outdoor use The current flag of the state of Oklahoma (the second in the state's history) was adopted by Act 383 of the Oklahoma state legislature on February 16, 1895: “ The flag of the State of Oklahoma shall be a crimson cross of St. Andrew on a field of white. The bars forming the cross shall be not less than six inches broad, and must extend diagonally across the flag from side to side." - (Code 1896, §3751; Code 1907, §2058; Code 1923, §2995; Code 1940, T. 55, §5.) ” The cross of St. Andrew referred to in the law is a diagonal cross, known in vexillology as a saltire. Because the bars must be at least six inches wide, small representations of the Oklahoma flag do not meet the legal definition.
