The bulletin board in the police precinct was very much a team effort between all the graphic designers on the crew. Everything on the board was both an easter egg - often specifically provided by the writers - and a visual reference to the bulletin board in the final scene of The Usual Suspects. I was responsible for three pieces out of everything that you see above - the bulletin board brand, a real estate brochure, and a flyer for a bodyguard service.
For the real estate brochure selling the mansion, we didn't have any great images of the mansion available for use, since most of the exterior shots are at night, so the best solution was to do a watercolour illustration
In our visual reference, there was a flyer with a very bold typeface that stood out to me, so we decided to create a version of it that lives in our universe. I didn't have access to the specific typeface in the reference, but was able to adjust a similar typeface to be a fairly close dupe.
After everyone's designs were approved and final, we all worked together to assemble the bulletin board.
