Yeah, I came across that when I was researching some of the state flags. A lot of the southern states earliest flags date back to the Civil War, but otherwise most of them were hastily thrown together for the 1894 World's Fair. Two obvious exceptions are the flags of Texas and California which were both adopted when they broke away from Mexican rule.I think I read (somewhere) that many state flags were hastily slapped together for the World's Fair simply because they required a display of one flag for each state, and some didn't have anything to provide. Don't quote me on that though.
