Here's your culprit; goes by the name of Sonny: http://www.flickr.com/photos/rainclouds/. Here people are getting arrested by police finding YouTube videos of crimes.. I'd think an online photographical homeage to one's own graffiti isn't much different.. Another friend paying respect at http://www.flickr.com/photos/senor_codo/sets/72157594147492474/ and see http://www.flickr.com/search/?q=sonny+chicago&s=rec for more. PS: let me guess.. your picture was taken right on the corner of N Western Ave and W Augusta Blvd, right in front of the abandoned Hi-Fi Video place that's been for rent for ages? Check http://www.flickr.com/photos/senor_codo/209034927/ for the resemblance to your picture and click on Street View on the following page for a 360 degree view of the surroundings ;-) http://maps.google.com/maps?q=988+N+Western+Ave+Chicago+IL+60622 (turn 90 degrees to the right and you'll see). You can recognize the metal fence, the black box that was painted on and the bench with the sign on it.
