There are 87, 3-D illusion pictures in this book -- all hidden within another visual dimension. After concentrating for a while on the initial image, the hidden picture begins to appear out of nowhere. Lots of fun.
I combine shipping for multiple purchases of printed material. This usually saves the buyer money.
