Original 1st printing (union logo #72) 13&1/4 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. *New Year's Eve concerts
 
 Art by (and SIGNED in pencil by BOTH) Stanley Mouse and Alton Kelley, image is # 41 in the Family Dog/Avalon series.
 
 Medium flat vellum stock poster is in good (B) condition; there are multiple randomly-placed pin/staple holes in all four corners and scattered around the outer margin area, along with a fairly pronounced crease/crunch in the lower right corner tip, a pair of lightcoffee-cup ring stains at about 9:00 on the left side of the image area, a bit of minor handling/moisture warping to the paper,   a VERY thin diagonal bend along the lower margin area, a touch of toning and a stray pin-prick spot/scuff or two hidingwithin the image area, otherwise it is a very presentable DOUBLE-ARTIST-SIGNED example of this always-in-demand 1st printing Mouse/Kelley Avalon poster.
