Original 1st printing 14 x 22" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) with Santana and Chicago (Transit Authority) appearing at the Fillmore West in San Francisco, CA on 9/12-14/1968. Art by Rick Griffin, image is # 136 in the Bill Graham/Fillmore series. Medium flat index stock poster is in fantastic mint/near mint (A/A- to A-) condition; other than a whisper of almost-negligible handling, I really can't see any conditional issues on this piece- it's a STUNNING example of the "Heart & Torch" poster.
