I just came across these amazing Dexter posters designed by Ty Mattson. They're three-color screenprints on black paper and they're totally amazing. I can't believe how well they capture each season (although I'm only caught up through season two). I talked Jake into letting me buy Season 1! Possibly the most awesome part of this is that Ty created these, posted about them on his blog, and the next day the producers of the show came knocking. You can buy them on the Showtime website.
