The Ohio Burgee is the official flag of Ohio. It is a triangular swallowtail flag, the only non-rectangular U.S. state flag. Its red, white, and blue elements symbolize the state's natural features and order of admission into the Union. A prominent disc in the flag's triangular canton is suggestive of the state's name. This flag was adopted in 1945. The flag was designed in 1901 by John Eisenmann for the Pan-American Exposition and adopted in 1902. Before that, for nearly a century after statehood, Ohio did not have a legally authorized state flag. One unsuccessful proposal had called for a design based on the state seal. Ohio has adopted an official salute to the flag and the official folding procedure gives it 17 folds. The Ohio flag has influenced a number of logos and municipal flags within the state. A scarlet-colored gubernatorial flag is based on the state seal. (Source: Wikipedia.org, CC BY-SA)
