Original 1st printing 14 x 20" concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with the Sir Douglas Quintet and the Orkustra at the Avalon Ballroom in San Francisco, CA from 5/5-7/1967.

 Art by Rick Griffin with a photo by Bob Seidemann, image ("Motherload") is # 60 in the Family Dog/Avalon series.

 Medium flat index stock poster is in excellent (B+) condition; aside from a tiny hairline 1&1/2" diagonal bend in the lower right corner/margin, a couple of ultra-tiny pressure dings scattered around the outer margins/corner tips and a 2 x 2" piece of clear tape on the reverse side covering up a small tape pull (top center margin) it is a FANTASTIC 1st printing example of this always-popular Rick Griffin Family Dog image.
