A beautiful mint condition FD-27 concert poster for Howlin' Wolf and Big Brother & The Holding Company (featuring Janis Joplin) at the Avalon Ballroom. This poster was only printed once, as the concert was cancelled–making it especially desirable, both for the strong image, and its scarcity. Designed by Stanley Mouse and Alton Kelley, this is considered one of the classic images of the Family Dog series–and we've never seen a copy remotely this nice. This poster was originally owned by Ralph J. Gleason (1917-1975;) one of the most influential music critics of all time. A central figure in the San Francisco rock scene, he 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. When the organizers of the Monterey Pop Festival had trouble recruiting the San Francisco bands, they turned to Gleason and Bill Graham, who were able to convince the major acts to come on board. We purchased this and the rest of Gleason's poster collection directly from his family.
