Our Acadiana motorcycle flags are made of a top quality polyester material that is machine washable. They are hemmed with a durable nylon thread and include extra stitching to help prevent fraying. The double-sided flags come with a generous 3/8" sleeve which is compatible with a pole mounting. (Pole mounts are sold separately.) 9"x13" is approximate, actual size may be closer to8.5" x 12.5" Acadiana, or The Heart of Acadiana, (Cajun French: L'Acadiane) is the official name given to the French Louisiana region that is home to a large Francophone population.In 1965, Thomas J. Arceneaux designed a flag for Acadiana. Arceneaux was a professor at University of Southwestern Louisiana, now University of Louisiana at Lafayette and had derived the flag from the university seal. In 1974, the Louisiana legislature officially adopted Arceneaux's design as the official Acadiana flag. The three white fleurs-de-lis on the blue field represent the French heritage of Acadiana, the gold star on the white field symbolizes Saint Mary, Our Lady of the Assumption, patron saint of Acadiana (the star also symbolizes the active participation of the Cajuns in the American Revolution, as soldiers under General Bernardo de Gálvez, Spanish governor of Louisiana). The gold tower on the red field represents Spain, which governed Louisiana when the Acadians arrived.
