Ellis Nadler's "Cards of Wu" is a hopefully never-ending series of woodcuts in the form of divination cards.
Thank you Ellis for sharing your work here—and for contributing that amazing Evil Orchid Garden bookplate. I have long kept up with the adventures of the Implausibility Detection Unit on Ellis's sketchbook/blog and suggest you do too.
I hope to post some of his non-Wu work soon.
***5/27/10 update: Ellis just let me know that the cards are currently being made as a hand-printed fine art limited edition (details available later this year). However, due to great interest he has now made them available to buy online as high quality digital prints.
9/2011 update: See the sequel
"A satire on the Tarot in a set of 78 woodcuts. Original prints are 30cm x 20cm on Zerkal White paper. This is a work in progress and images are being added on a regular basis. Full colour archival quality giclée prints are available now. A deluxe collectors' edition is planned as a boxed deck of outsize cards with a decorative patterned back."
