I'm not a photographer or graphic designer, but if you want to get some shots of some iconic Chicago exteriors, you may be able to work something out with Fenway Park. The Red Sox are on a road trip, and I know they have tours when the team is out of town, so perhaps they could accomodate your needs. Just a thought. Otherwise, check into the waterfront areas, particularly around the Constitution museum, again for iconic imagery. See my term paper.
