I visited 65GRAND over the weekend and a short walk down Grand Avenue from the Blue line station took a bit longer as I stopped to document all the street art I found along the way. I'll identify the artists as I am able, aided by Joseph J. Depre's Chicago Street Art book. While I will note when I am less sure about an artist, the nature of street art, and especially its decay, makes it difficult to positively identify an artist.
(Joseph J. Depre's Chicago Street Art is available here, and at Chicago Comics, Uncle Fun, Quimby's BookStore, Myopic Books, and Museum of Contempory Art Chicago. Depre also corrects the artist identifications--updated on 6/29.)
