Art Source International has amassed a collection of authentic antique maps and images brilliantly highlighting and detailing the state of Iowa, which borders Minnesota, Wisconsin, Illinois, Missouri, Nebraska, and South Dakota. The Missouri river separates the state from Nebraska, the Big Sioux River separates it from South Dakota, and the Mississippi river separates it from Illinois and Wisconsin. Iowa was admitted to the Union on December 28, 1846, as the 29th state. Art Source International reproductions and vintage maps can be ordered framed or without a frame.
