Original 1st printing 13&1/8 x 19&1/8" 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 vellum stock poster is in BEAUTIFUL near mint (A-) condition; aside from a few light soft handling bends scattered around the image/outer margin area and a tiny edge ding or two, this example is just about as crisp/sharp as they come.

 

 An absolutely SUPERB-looking 1st printing example of this classic Mouse/Kelley Avalon poster.
