I have spent a lot of time in recent times over near Wells Street as a result of the bridge replacement program that they have been going through.  That puts me outside the Merchandise Mart building along the river.  Along the front of the building is a hall of fame of old Chicago figures.  A series of pillars are lined up along the river with each having a bust of a famous person on top.  These are nicely aligned and caught my eye as I was walking by.  As an aside, if you watched the TV series Boss, you will have seen these busts as part of the title sequence.
