A demonstration in San Francisco, March 1969, shot by Robert Altman. The photographer recalls: "In 1998 Harold Evans published his tome 'The American Century' and selected this photo for a double page spread. Daniel Moynihan reported seeing a well-thumbed copy in the Oval Office." 'The Sixties: Photographs by Robert Altman' will be at London's Idea Generation Gallery from July 16 - August 29 2008.
