This counter-culture icon celebrated the 1967 Joint Show of the Big Five psychedelic poster artists Alton Kelley, Victor Moscoso, Rick Griffin, Wes Wilson, and Stanley Mouse (plus sculptures by Gerard Nicholson, paintings by Ralph Chesse, and lights-in-motion by Richard Leonard. The show was at Moore Galleries on Sutter Street in San Francisco with a Preview Showing on July 17, 1967 with music by Country Joe and the Fish. Each of the Big Five also created posters specially for the show. It was an important moment in the history of American art.
This invitation was part of an exceedingly rare larger package that can be seen in another of my Buy It Now items.
