Official promoter-issued 2nd printing 14 x 20" concert poster for Country Joe & the Fish appearing with Lee Michaels and Moby Grape at the Avalon Ballroom in San Francisco, CA from 12/30-31/1966.
Art by Stanley Mouse and Alton Kelley, image is # 41 in the Family Dog/Avalon series.
Medium flat index stock poster is in BEAUTIFUL near mint (A-) condition; just a couple of nearly-invisible pinch dings hiding within the image area and that's pretty much IT.... VERY clean otherwise.
As an added bonus, this example has been HAND-SIGNED and inscribed "Peace & Love" by none other than Country Joe McDonald himself!
