Original 1st printing 14 x 19&1/4" concert poster for Big Brother & the Holding Company (with Janis Joplin) appearing with Fleetwood Mac (featuring Peter Green) and Dr. John the Night Tripper (*canceled), at the Carousel Ballroom in San Francisco, CA from 6/21-23/1968 (actually 6/20 & 22- the 6/21 date has been crossed out).

 

 Art by Bob Seidemann, medium flat vellum stock poster is in good to very good (B to B/B+) condition; there are a series of thin creases and handling bends running along the outer margin area, plus a few loose pin-prick age spots scattered around the image area, a light amount of toning/surface dirt and a couple of thin diagonal corner creases, otherwise it's a decent-enough looking gently-used example of this very strange-looking late-period Carousel poster.

 

 These shows were only a couple of weeks before Bill Graham took the venue over and renamed it "Fillmore West".
