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 Krefting, 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-/B+) condition; there is a tiny pair of pin-prick black smudges in the "B" of "Big", a nearly-invisible thin vertical surface scratch in the black pass of ink and a couple of ultra-light handling dings here and there, otherwise fine.
Superb-looking original 1967 Big Brother/Janis Joplin poster from a tiny San Francisco benefit show.
