Quick, It's the Trouble Alert

Cincinnati Museum Center at Union Terminal, Cincinnati, Ohio, USA

For those of us from a certain generation, Saturday mornings were spent watching the Super Friends (Superman, Batman and Robin, Wonder Woman, Aquaman, and their sidekicks) save the world.  Based at the Hall of Justice, the Super Friends used their superhero powers for the good of all.  In the Hall of Justice, the Trouble Alert notified the Super Friends of the latest threats to mankind.

The fictional Hall of Justice was based on Cincinnati's Union Terminal (now the Cincinnati Museum Center at Union Terminal) and it was thrill to see a fond memory of childhood fiction come to life.
