Original 1st printing 14 x 20" concert poster for Quicksilver Messenger Service appearing with Kaleidoscope (featuring David Lindley) and Charlie Musselwhite at the Avalon Ballroom in San Francisco, CA from 1/12-14/1968.

 Art by Rick Griffin, image ("Eternal Reservoir (or the Source") is # 101 in the Family Dog/Avalon series.

 Medium flat index stock poster is in excellent (B+) condition; there are a couple of nearly-invisible handling dings/stress creases scattered around the image/margin area, a tiny 1/2" diagonal bend in the top left corner tip, a tiny black india ink spot in the right center border of the image, a stray edge ding or two and a VERY soft horizontal bend traversing the center of the image area, otherwise fine.

 An absolutely GORGEOUS 1st printing example of this iconic Rick Griffin Quicksilver image from the Avalon.
