The growing literary style called New Journalism describes the 1968 book that features a 1939 international Harvester school bus.
Further, also known as Furthur, is a 1939 International Harvester school bus purchased by author Ken Kesey in 1964 to carry his "Merry Band of Pranksters" cross-country, filming their counterculture adventures as they went. 
 Due to the chaos of the trip and editing difficulties, the footage of their journey was never released as a movie until the 2011 documentary film "Magic Trip" -- although the bus featured prominently in Tom Wolfe's 1968 book "The Electric Kool-Aid Acid Test". 
The Electric Kool-Aid Acid Test is a nonfiction book by Tom Wolfe that was published in 1968. 
 The book is remembered today as an early  and arguably the most popular  example of the growing literary style called New Journalism.
