** Update 3/27/2012: While I hadn’t seen the original design that ultimately inspired this poster when I created it (my inspiration came from a derivative that was, no doubt, 2-3 times removed), I have since been made aware of the source of the design for this poster and I want to give credit to that source. This design appears to have originated from Team Detroit, a design firm in Michigan. This site talks about the design and who created it. Really great stuff.
