by Walter Wick

First Impressions

A dime, a die, a skull, a screw, a 4, and more
have been pressed into clay
Right?
Right!
Now turn the page upside down.
The clay impressions pop out!
That's an illusion.
Turn the page right side up,
and the illusion goes away.
Now try this trick.
Make a 4-inch hole in a piece of paper.
Place it on the picture
and watch the impressions pop out again.
