Animator and artist extraordinaire Dusty Abell has uploaded a Star Trek: TOS poster to his Deviant Art page that is nothing short of phenomenal.
The idea according to Abell was to feature some element from each of the original 79 episodes of Star Trek: The Original Series. There's simply so much to love about this piece: the Enterprise has never looked better, the likenesses of the actors/characters - while being caricatures - is amazing, the setting itself (check out the Triskelion flooring!). Also, Abell stated he put Lazarus on top of Vaal figuring he'd be falling off something sooner or later. Priceless.
A poster seems too small for this artwork. I wish I had a projector to shine this image up on a wall to stare at it all day! (originally found on the John Byrne Forum)
