There’s a Wayne Avenue, of course referring to the Wayne Family, and there’s also Kane County in the left hand corner, referring to Martha Wayne’s side of the family.
If you simply glance at this map of Gotham City and its subway system from the Joker set (passed along by @UberKryptonian), it looks relatively normal, right?
Fans will also recognize the Amusement Mile district, home of the amusement park where The Killing Joke took place.
There’s also an Otisburg, which I’m hoping is a nod to Lex Luthor’s inept henchman Otis from Superman: The Movie.
