Jeff Stewart's Appearing cans have been called the greatest production item of the twentieth century. After selling tens of thousands they are finally discontinued. If you are one of the people who has one you really need this book. It is full of ideas by David Ginn, Frank Herman, George Schindler, Jeff Stewart and Meir Yedid. The Soda Can In Balloon alone is worth ten times the price of this book. 43 items, 32 pages. Written by Jeff Stewart and illustrated by David Preisman.
