If you zoom in you’ll notice there’s a baseball stadium between Brady and Archer from Cincinnati to Detroit, a block west of the current ONEOk Field. The drawing could be a reference to Association Park, which was located between Archer and First from Elgin to Cincinnati according to a timeline of Tulsa’s baseball stadiums. Association park, however, closed in 1917.
Regardless of accuracy, the map provides a nice reminder of how much Tulsa has grown (or sprawled) in the last hundred years. Even by 1926, Tulsans considered the current fairgrounds, then a cow pasture, “so far out in the country.”
