Banksy in Chicago

I saw this early last month while walking home from studio, but in the craziness that is finals I didn’t take a shot of it.  There is some speculation as to whether this is a true Banksy piece, but I for one think it is.  These pictures are from the Chicagoist website and I saw this article a few days after I saw the tag.  Banksy a few feet outside of my house doing his work?  That’s crazy.
