You just never know what you are going to find on Michigan Avenue.
Over the summer, it was refrigerators (here and there and over here and over there). Now, it is Lego statues. I think there are six or seven sprinkled along Michigan Avenue between Grand Avenue and Chicago Avenue. These are to promote a Lego Show/Kid's Fest that will be at McCormick Place.
I like the little diver that is "stuck" behind the shark's goggles - it's shown in the lower right photo in the collage.
