Here's a recreation of an opening-year poster. The Bugs Bunny illustration came from a scanned media kit and was cleaned up substantially to be HD quality. I also changed it to Six Flags, just for fun. If you're in the Gurnee area, the Warren Newport Public Library has a fantastic file folder full of GAm ephemera!
