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*, at the Carousel Ballroom in San Francisco, CA from 6/20-23/1968. (*- Dr. John canceled; a good number distributed examples have his name crossed out with magic marker- this one is NOT marked)
 
 Art by Bob Seidemann, medium flat vellum stock poster is in excellent (B+) condition; there are a few light handling bends/tiny creases and a pin-prick spot or two scattered around the outer margin area, along with a tiny pin hole in the ticket outlet strip, a light pull in the extreme lower right corner, a couple of thin bends along the upper right margin/edge and a couple of semi-soft handling/pinch bends hiding within the image area, otherwise fine.

 These shows were only about a week before Bill Graham took over the lease for the venue and renamed it "Fillmore West".
