Changing Faces - optical illusions with paper

Changing Faces - optical illusions with paper
This book on optical illusions using paper certainly looks interesting!

From the product Description
Changing Faces presents an idiosyncratic and humorous collection of paintings, drawings, cartoons, masks, toys, advertisements, and other works of ephemera that -- either by flipping or flopping or just plain staring -- somehow transform the human physiognomy. Here you will find optical illusions from the Renaissance, Enlightenment-era political cartoons, and Victorian toys that all start off as one thing and end up as another. Sometimes these mutations were made for fun (give magnetic hair to a bald man!) sometimes for profit (buy a Studebaker!), and sometimes to score a political point (watch a French king turn into a big fat pear!), but the results are always an intriguing pleasure to watch.

Here's the link for the book Changing Faces
