Original 1st printing 8&1/2 x 11" concert flyer 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 canceled).
Art by Stanley Mouse (who also SIGNED the poster in black flair pen) and Alton Kelley (with the central image borrowed from Franz (Von) Stuck), image is # 17A in the Family Dog/Avalon series.
Thin flat stock flyer is in VERY sharp near mint (A-) condition; aside from a couple of nearly-invisible pinch dings, a thin horizontal machine crease along the top margin and a whisper of surface wear, this one is just about as sharp/crisp as they come.
GORGEOUS ARTIST-SIGNED example of this now 51-year-old concert flyer from the Avalon.
