Buttnekkiddoodles

Hung out with Jennymouse2003 in a department store in downtown Chicago before I had to head off to get my next generation booster shot.
Can you guess which department store in which building this sketch was made? There are 2 clues.
BTW, I think it was John Lenin who said,”The time you enjoy wasting, is not wasted time.”
Drawn with a Pitt Artist Pen Fude nib and a few Grey Pitt Artist Pens on a Clairefontaine Goldline sketchbook.
