Dark Ink Art. It's titled "Springfield Gorge" and is based on The Simpsons, season 2 episode, "Bart the Daredevil".
I'm stoked that I got to do this poster. If I have my way, I'll get to do some more focused on different episodes. It'll probably depend on how this first one does, so, be sure to grab one if there's another episode you'd want a poster of!
And another thing! How come I can't get no Tang around here?
