On the crossroads of Kercheval and St Jean in Detroit, there appears to be somewhat of an old school house that at the very top center, has a sculpting of Mickey Mouse on it. What's really strange is there are only rumors of why it's there, yet I've not seen one piece of legit information from anyone or on any kind of Disney site.
