Disney World has always been a great source of behind-the-scenes material of upcoming Pixar films, as the Magic of Disney Animation exhibit has often displayed concept art and maquettes for films currently in development. Disney recently put up a load of artwork for Cars 2, which Stitch Kingdom did a fantastic job in covering. Looks like there are a nice assortment of pieces displaying all of the various locales of the film, including London, Tokyo, Italy, and Paris. Head on over to Stitch Kingdom to view the great collection!
