Official promoter-issued 2nd printing (RP-3, flat/matte stock) 14&1/8 x 20" concert poster for Country Joe & the Fish appearing along with the Sparrow (proto-Steppenwolf) and Kaleidoscope (featuring David Lindley) at the Avalon Ballroom in San Francisco, CA from 2/3-4/1967. 

 Art by Victor Moscoso, image ("Dance of the Five Moons") is # 46 in the Family Dog/Avalon series. 

 Medium flat index stock poster is in near mint (A- to A-/B+) condition; really nothing more than a couple of fairly negligible edge/corner-tip dings and a soft pinch bend or two hiding within the image area, otherwise it is an absolutely STUNNING 1st printing example of this early 1967 Avalon poster. 

 As an added bonus, this example has been HAND-SIGNED (in black sharpie) by Sparrow (and later Steppenwolf) lead singer John Kay!
