Rick Synchef has a huge collection of books and periodicals showcasing the work of Beat poets and authors of the 1950s and '60s, from Charles Bukowski to Gary Snyder. Almost every book on his shelves was signed by its author, and in many cases by the people associated with the title, too.
The two most impressive books in Synchef's collection were Jack Kerouac's 'On the Road' (a first-edition paperback from 1958) and Tom Wolfe's 'The Electric Kool-Aid Acid Test' (a first-edition hardcover from 1968). On October 10, 2013, these books, along with several hundred other publications and objects, are up for auction at PBA Galleries in San Francisco.
