Last month a t-shirt design contest for The Dark Knight Rises was announced. The designs are being judged by Warner Bros., and the top 3 finalists will be sent to director Christopher Nolan who will make the final decision. The top prize is $3,500 and 12 shirts (from the website) of their choice.
I've included a bunch of the designs here that have been submitted. There's a ton more to check out, and you'll be able to place your own vote if you want on the official site. Some of these are actually very cool! Look over the designs and place your vote!
