Original 1st printing 13&5/8 x 18&5/8" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with the Steve Miller (Blues) Band and Robert Baker at Steninger Auditorium on the campus of the University of California (San Francisco) Medical Center on 3/4/1967.
Art by Kreftins, event was a student-sponsored event billed as "Journey to the End of Night- A Benefit for Peace".
Medium flat vellum stock poster is in GORGEOUS near mint (A-) condition; aside from a couple of ultra-tiny edge bumps, this example is about as crisp/clean as they come- a KILLER early-'67 1st printing Big Brother poster from a tiny hometown benefit gig.
