8. Psychology Book With Unusual Cover Art (price unknown)
There are so many details on this book cover that we don’t know where to start. Apparently, the book is part of a collection with 23 more books on how to understand human behavior.
The more you look at this cover, the more weird details you find. Just look at those teeth on the bottom side of the cover, or the teeth of that big creature that looks like a weird combination of a dinosaur and a sea monster.
It definitely could be great material for psychology classes (in college, of course). Anyway, some of our readers told us they actually had this book along with others from the collection, so I guess it was quite popular.
