There's quite a mixture of stuff in "Stuff", including material reprinted from "Pabular" magazine and a few marketed items. It contains plenty of card sleights and tricks (some of it quite difficult) but also things with coins and miscellaneous close-up effects, often with gimmicks and things you have to make up. His impromptu rising card, which is the basis of many subsequent versions, is in there too.
Hank Lee's online catalogue has a bit of a description: http://www.hanklee.org/xcart/customer/p ... uctid=6432

I must admit I haven't looked at it for some time now, but it's a wonderful book to have and to look through.
