Central and Southern Illinois has a mix of fans of the out of state team St. Louis Cardinals. Offering state fair attendees a chance to meet and be coached by former Cubs and White Sox stars might encourage kids to follow an in-state team.
As it was, this poster was the only thing I saw that represented the Chicago Cubs at the Illinois State Fair. Sadly, this poster was not even available for sale. I'm told that they could've sold a lot had it been available for sale.
