A superb near mint first printing FD-11 concert poster, advertising a show by the Grass Roots and Big Brother & The Holding Company at San Francisco's Avalon Ballroom, in June 1966. Known as "Stone Facade," this is the first Avalon or Fillmore poster done by future legend Victor Moscoso. This first printing on vellum measures 13 35/64" x 20" and is in virtually mint condition, with the only flaw being a small and almost unnoticable tape pull at the top center border. This poster comes the collection of the late Ralph J. Gleason (1917-1975;) one of the most influential jazz and pop music critics of all time. He was a central figure in the San Francisco rock scene, helped organize the Monterey Pop Festival, and co-founded Rolling Stone magazine. Bill Graham himself credited Gleason with suggesting the Fillmore Auditorium to him as a site for concerts, while the Family Dog met with Gleason at his home to discuss their idea to stage dance concerts, prior to their first show at the Longshoreman's Hall. This is a rare opportunity to obtain a poster from the personal collection of one of the key figures of the San Francisco Scene. On request, we will gladly provide a certificate of authenticity stating that this poster came from the Ralph J. Gleason Collection.
