You Can't Spell Architectural Facade without 'Face'!

Weird title I know but it's all I have at the moment, clever-wise... Essentially, I'm posting this because I forgot to mention something in that last incredibly long post! I found the random faces that were carved into the building when I was walking around near the library the other day! Here are the pictures! These were on a building at the corner of Congress and Dearborn. I hope you find them as charismatically whimsical as I do!
