I had a feeling I knew what kind of "Peep Show" this would be. It was, after all, a window in the Tribune Building on Michigan Avenue, not a "book store" on Wells Street. But I had to look to make sure.
Then I had to take some pictures. There's a bit of glare from the glass so I'm not sure if you can make out that the Peep scene on the lower right is Bunny and Chick Peeps roasting marshmallows around a bonfire. Seems like that is some form of Peepocide or Peepibalism
