Illinois Commemorative

Anything on the reverse? Obviously, the man in the middle is Lincoln circa New Salem days. The distinguished gentleman on the left is probably a composite Illiniwek Confederation Indian. Below him would be an engine from the Illinois Central railroad, one of the first rail systems in the US. Lower left would prove to be very enigmatic unless you are intimately familiar with the entire state of Illinois(or perhaps a Mormon). Nauvoo was once the home of the Mormon Church and founder Joseph Smith was lynched in the nearby county seat of Carthage. It is a sunstone from the original Nauvoo Temple. Unfortunately, the guy on the left has me completely flummoxed. It resembles a presidential US Grant but he has fairly weak links to Illinois and none after the Civil War. He worked in a tannery owned by his father in Galena for ~2 years before the Civil War broke out and he briefly commanded a regiment in Cairo at the beginning of the war, both pretty meager ties. It could very well be someone else but only The Shadow knows!
