Original 1st printing 20 x 14&1/8" concert poster for Quicksilver Messenger Service and Country Joe & the Fish appearing together at the Avalon Ballroom in San Francisco, CA from 5/19-21/1967.

Art by Rick Griffin, image ("Sutter's Mill") is # 62 in the Family Dog/Avalon series.

Medium flat index stock poster is in near mint to excellent (A- to A-/B+) condition; aside from a couple of tiny pressure creases and a sliver of toning along the lower left edge of the bottom margin and a nearly-invisible handling ding or two hiding within the image area, this example is in tip-top shape.

 GREAT-looking example of one of the more reasonably-priced Griffin posters in the FD series.
