There are a few missing. Specifically a toy surrounded by hype. http://wahfunny.com/anatomy-of-toys-30-pics/
My sister has some of those prints from a while back, after a while though I feel like the whole joke gets old. Most of them all kind of look the same. And I mean, really, gummie bears are clear. You'd see their organs, it would be like jelly fish.
^ While I agree that it is all a bit repetitive and the same idea, I still really enjoy seeing them and new versions. I think this is because the creation of the anatomy and the shapes used to describe it are all completely new and different. These differences of each cartoon character really pushes how he constructs/creates the anatomy. The more unique examples are how he chose to deal with Mr. Potatohead and the very hungry caterpillar.
I don't know if I've seen those. I laugh at some, I liked the initial concepts. But after a while, everything is just dissected without any real difference in the anatomy from what I've seen. And we all know how KAWS has been milking that too.
