Original 1st printing (standard edition/textured stock) 22 x 27&7/8" event poster for the 7/17/1967 opening of the Joint Show, held at the Moore Gallery in San Francisco, CA and featuring music by Country Joe & the Fish, plus exhibited art by Rick Griffin (who did this version of the poster), Wes Wilson, Victor Moscoso, Stanley Mouse, Alton Kelley and several others.
Art by the aforementioned Rick Griffin, image is featured in the Art of Rock book on page 234 (plate 2.347).
Medium-thick textured index stock poster is in beautiful near mint (A-) condition; just a few stray soft pinch dings scattered around the image area and that's IT... essentially, this example is pretty much as crisp/sharp as they come.
KILLER specimen of this iconic 1967 Rick Griffin image from the AOR. Check out this photo of Rick and Kelley at the opening! (photo: Ted Streshinsky)
