It's the second edition of a 1961 Shel Silverstein (of Where the Sidewalk Ends fame) Uncle Shelby's ABZ Book.
I'd never heard of it, but as a fan of Silverstein from childhood, I grabbed it.
Then I saw that it was the second printing! I'm sure it would be better if it were the first, but that's still cool!
And then I started reading it! Oh. My. Goodness. It cracks me up! It's so un-PC. I mean, really- "Mommy loves the baby more than she loves you." !!!! What the heck, right?
And this gem is on the last page: "The paper in this book is not really paper. It's made from candy. The End."
The whole book pretty much tries to get kids in trouble with their parents- by saying that, by throwing raw eggs on the ceiling, a person who lives up there will catch them for you. Oh, and that "Q is for Quarantine" and that it means that kids should go in 'cause there's candy!
Just insane. But what a totally awesome 75 cents spent, right?
