While searching through the picture files on DisneyShopping.com I came across this line of character busts. They don't appear to be available for purchase yet. Wow! These are cool!
Looking elsewhere on the net turns up the info that these are made of polystone and are done by Enesco. Sideshow Collectibles has them listed as limited editons of 1000 for $79.95. They are around 8" H.
