I found this book today from looking up the source of a random lol pic:
http://en.wikipedia.org/wiki/Man_After_Man:_An_Anthropology_of_the_Future
It's basically a speculative future book about all these crazy genetically engineered breeds of human offshoot made for singular purposes after the pure blood humans evacuate the planet and they're left to fend for themselves. Which is all fine and good but the art is HORRIFYING. Do an image search and be prepared to be scarred.
There are giant, boneless looking walrus-men, weird cyborg midgets integrated into the flesh of their deer-like mounts with HUMAN FACES, THIS!
It's pure nightmare fuel and is unfortunately very expensive, used copies are like eighty bucks.
