In slide number 16 there was a book that I had mentioned is part of a picture series of people reading fake books on the subway. This is another example of one of those. This one is a little more clearly a joke. Human taxidermy would have to be illegal, or at the very least, unpopular. It's not totally out of the realm of possibilities though. I can see some rich person having a human lampshade just to flaunt their wealth.
What would be really disturbing is if someone started talking to this guy about human taxidermy. "Hey buddy. If you're into that stuff I know a guy. He can get you any skin color you want." You'd tell him it's just a prank and he'd say "not for me it isn't. Not for me..."
