FIRST EDITION, INSCRIBED BY KEN KESEY AND FELLOW MERRY PRANKSTER KEN BABBS, "For Michael, Tommy Wolfie Kesey and Ken 'Har Har' Babbs." The Electric Kool-Aid Acid Test was considered to be one of the first great books published in the New Journalism style, the New York Times calling it "not simply the best book on the hippies, it is the essential book...the pushing, ballooning heart of the matter... Vibrating dazzle!" The book follows the adventures of Ken Kesey and his "Merry Pranksters" who traveled across the country in a colorfully-painted school bus which they christened the Furthur.
