Was looking for the first use of the enso Suzuki drew that's so well known. It was hard for me to find on cuke - because I didn't think clearly and write the right stuff in the site search box. Once I had it I realized it should have been easy but I also realized that others will give up looking for it. So I gave it its own page and linked to it from a few places. He drew it at Mike Dixon's request for a poster for an art exhibit and sale to raise money for a Zen Mountain Center early on before we even knew we could buy Tassajara. The show started December 16, 1966 and ran for a month. Just before New Years we learned that the money that was raised by this and other means would go for the down payment on Tassajara. It's all explained here on the new ZMC Benefit Art Exhibition and Sale poster - Enso First Use page.
Thanks Mike and thanks Suzuki Roshi!
