The best part of Gregory Wilson's Stockholder is surely the huge book of routines that came with it. This book has ideas using the principle that were contributed by some of the greatest minds in magic, Mike Close, Paul Harris, Roy Johnson, Michael Weber, Daryl, Dan Harlan, and others.
You won't use all 17 ideas but chances are good that you will fall in love with a couple of them.
There is no better way to breath life into the old Out To Lunch principle.
The good news is that I have unearthed a small supply of these books (NOT the wallet) ...they are $25.
I do not carry the wallet. Just the idea book.
