Furthur was a 1939 International Harvester school bus purchase by author Ken Kesey in 1964, for $1,250 from Andre Hobson in Atherton, California. The bus was stripped down and remodeled inside and out for a psychedelic excursion across the country with Kesey and his Merry Pranksters on board. The destination sign on the bus was painted to read "Further." When Kesey went to Mexico to avoid drug charges, the Pranksters took the bus down to see him, re-painting the manifest to read "Furthur" in a deliberately meek attempt at disguise. This latter spelling is the origin of the popularly misspelled name.
