This note Certifies that the Artwork you have received is a Genuine Ken Kesey Original Signed, Key--Z Productions." "According to his son Zane, Kesey began experimenting with marbling techniques in 1964 while traveling on the bus FURTHUR and dropping acid for the first time. Oil paint floating in a puddle entranced the Merry Pranksters, and they began dipping objects into the mixture, creating instant objets d'art. Later in his life Kesey returned to this technique, psychedelically marbling, finishing, and signing around 15-20 books total. This is one of those scarce copies. A psychedelic lollipop swirl of original art from the acclaimed writer and countercultural icon. (Burnside Rare Books). Scarce in the original striking marbled wrappers by Kesey and only 1 of 5 extant copies of this edition of One Flew Over the Cuckoo's Nest. Scarce. First Edition, thus with "This Edition published in Penguin Books, 1999" with the complete number line.
