During a search at Flickr, I came across something interesting. Several sculptures that were meant to be used for toys of Roger Rabbit and friends(and enemies) Though they were according to the uploader of the picture never released.
Take a look for yourself
I sure would've liked to own these myself, but according to the picture comments they were sold away on ebay some time ago. Oh Well. Would be nice if the winner of that auction found the blog and supplied us with some photos of the coloured figures.
