1961. Early Abbott's edition. Very good condition. Some discoloration on the cover around the edges, but all pages intact and tight.
Bruce Posgate offers a wealth of great information about working for Kids, in 52 pages. No tricks in this book -- just experienced wisdom about best ways to get the most from your kidshow.
A classic for good reasons. If you don't have this book, and you do kidshows, you should buy it!
