At the other end of the park, visitors would enter a clear plastic walkway leading to Superman's Fortress of Solitude....
Entering through the keyhole, visitors would see giant statues of Jor-El and Lara, as well as "moving replicas of alien beasts" in the Interplanetary Zoo (and security guards wearing Superman costumes).
Another Fortress display would have featured Superman's Rogues Gallery (all five of 'em).
Other features of the theme park included a movie theatre, skating rink, "craft shops", an unusually large first aid station, a hotel, and a supermarket (get it? "super" market?).
UPDATE: My pal Rich informed me that today is the day the 2008 Superman Celebration kicks off in Metropolis! I know I linked to their website above, but I honestly didn't catch the date at the time. Wow....maybe I was being guided by the Spirit of Superman!
To everyone in Metropolis: Have a great time celebrating 70 years of Superman! I sure wish I could've been there this year (and I will get there some day), but I guess my Superman@70 month will be my small contribution the big celebration!
