When I published my book, Improv Wisdom, Don't Prepare, Just Show Up in 2005 there were no graphics or images connected to the book. Just this year the Chinese edition is being revised to include these thirteen cards, each representing one of the Maxims.
Many of my friends encouraged me to copy the cards and make them available as a set. I've been able to have them reproduced by a wonderful company called Moo.com.
They are available for sale. A single set, including postage costs $25US. Additional sets are $20. To order a set, message me via email improvwisdom@gmail.com. Payment can be made via VENMO. @Patricia-Madson or via PayPal using the improvwisdom@gmail.com. address.
These are a limited edition, so if you'd like them, I encourage you to order soon.
