Original 1st printing 14 x 20" concert poster for Love (featuring Arthur Lee) appearing with Big Brother & the Holding Company (featuring Janis Joplin) at the Avalon Ballroom in San Francisco, CA from 7/15-16/1966* (shows were canceled).
Art by Stanley Mouse and Alton Kelley (with the central image borrowed from Franz (Von) Stuck), image is # 17A in the Family Dog/Avalon series.
Medium-thick flat vellum stock poster is in VERY nice near mint to excellent (A-/B+ to B+) condition; aside from a couple of ultra tiny soft pin-prick indentations in the upper left corner, a tiny brown spot in the lower left margin/edge (just to the left of the first "A" of "Avalon"), a whisper of surface wear and a nearly-invisible thin hairline corner crease in the lower right corner, it is just about as crisp/bright as it looked when it rolled off the press over 50 years ago.
As the shows were canceled, these posters did not go through the same distribution channels as most of the other Family Dog posters- a good number of these were either discarded or remaindered.
