Split Personalities
I found this book, Making Faces, the other day in a storage box. There are eight faces, and each face is divided into five tabs (head or hat, eyes, nose & cheeks, mouth, and shirt). You can flip any of the face pieces to any of the eight versions.
Here's the back cover.
What do you think of that claim?
"You can make more than 65,000 other faces by mixing the pages of this book."
