The Batman Forever Promotion
The nine-by-fifteen-foot chalk mural of Batman's face that hung in the main lobby of Century Complex, Sacramento...
One of the three chalk murals of Gotham City. Each mural section was about nine by fifteen feet large...
Another one of the Gotham City murals...this one with the Batsignal in the night sky...
These are the murals on the floor...Maybe this gives you a better sense of scale?
Even though you can't actually see what's on the murals, you can tell the size involved and where they were placed in the lobby of Century Complex, Sacramento...
