Original 1st printing 14 x 22" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Santana and Chicago (Transit Authority) at the Fillmore West in San Francisco, CA from 9/12-14/1968.
Art by Rick Griffin, image is # 136 in the Bill Graham/Fillmore series.
Medium flat index stock poster is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; aside from just the slightest whisper of handling (one or two nearly invisible pinch dings), this example is as clean/sharp as they come.
A VERY clean/bright 1st printing example of Griffin's iconic "Heart and Torch" image, check out the photo* of the FW marquee! (*courtesy of CNN/Chicago)
