A near mint first printing concert poster advertising a February, 1967 concert presented by the Hells Angels and featuring Big Brother and the Holding Company (with Janis Joplin) and Blue Cheer at the California Hall in San Francisco. This scarce first printing (with the "Bindweed Press" credit) measures 14 1/4" x 20" and is in beautiful condition (there is some minor handling and two small torn areas at the bottom corners have been invisibly repaired by top paper conservator Chris Fennell of Chameleon Restoration (the work is invisible, but we always disclose restoration.) 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. Gleason obtained these posters at the Fillmore after shows, and sometimes folded them to fit in his famous trench-coat; this was one of those and was originally folded in thirds–but it has laid flat since the show and the folds are barely noticeable at all. There are tiny pinholes in the top corners, but again, these are barely noticeable and this will frame virtually mint. 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.
