Official promoter-issued 2nd printing 14&1/4 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 near mint (A-) condition;  aside from a tiny corner-tip bump or two and a nearly-invisible diagonal bend near the upper left FD logo, it is a SUPERB example of this always-popular Rick Griffin Family Dog image.
