Ultraman Anatomy !! OMG

we all been to the school and get a biology class, we had seen almost all creature anatomy, but this one.. is a bit creepy and cool at the same time.. ULTRAMAN anatomy !

I don't get it, is it a face or a mask ?!?

it's appear to be an scan of an old printing, well those days they really like to ration things up. almost any thing had their anatomy drawings. well we just take it as an interesting things to see.
