I'm in ohio, thanks for the input!
Thank you for providing your state name.
There are some architectural landmarks whose images have become company trademarks. Any illustrations you include in your Ferris Bueller map should avoid copying these logos (example: the Transamerica pyramid).
An addition: Because you mentioned that you manufacture
licensed apparel, I assumed (perhaps wrongly) that you have licensed for use the trademark "Ferris Bueller." The trademark "Ferris Bueller's Day Off" is owned by Paramount Pictures Corporation. Paramount markets apparel (primarily tee-shirts) based on the film (and toys).
So, you have a few rights that could be held by others that you will need to consider (and possibly obtain a license for) before marketing your Ferris-Bueller-based clothing items. A review of your map by an IP professional in your area would be smart and it is what I recommend.
