A superb hand printed 5″ x 7″ silver gelatin photograph of Johnny Cash taken in 1969 at San Quentin Prison, by the legendary Jim Marshall.  Cash was about to perform for inmates at this famed California prison when Marshall yelled out “Let’s take one for the warden”–and this photo captured Cash’s response.  The photograph is in near mint condition with a barely noticeable light crease, and Marshall’s handwritten title and notes on the reverse.  The late Jim Marshall was one of the most highly acclaimed music photographers ever; he was the chief photographer at the Woodstock Festival, the only photographer allowed backstage at the Beatles final concert, and shot legendary photographs of Jimi Hendrix, The Doors, Janis Joplin, Bob Dylan, the Rolling Stones, Johnny Cash and countless other music legends.  His photographs adorn more than 500 album covers including the Allman Brothers Band’s “At The Fillmore East” and the Jefferson Airplane’s “Volunteers,”  as well as many concert posters.
