SuPmon is a pretty cool Etsy shop I recently came across full of really neat (mostly Wes Anderson) film illustrations. Not only is the shop full of these, but the owner also has his own original works AND coolest of all, a customized I always wanted to be a Tenenbaum listing where you can be added to the Tenenbaum family! Neato!
(he also has a few illustrations from The Big Lebowski as well!)
