As I recall I remember seeing a piece of boogerart at a hot dog stand under the el at the stop by the Sears Tower. Not the type of place you go to enjoy your food. The owner had noticed that Chongo had been coming in every day and leaving a "calling card" under the table in a booth. After a few weeks the owner looked under the table and found a near perfect bas relief replica of the "scream" except of course the "screamer" was pygmy marmoset, the only colors were gray and green and it had "my mom the day I was born" scrawled in red at the bottom. It made pretty much everyone urge a little when the figured out what he used for the red.

Anyway its probably still there hangin' there. Right over the door preserved with a weekly coating of lemon Pledge and dead flies. It ain't pretty but it sure is a conversation piece.
