Original 1st printing 13&7/8 x 20" concert poster for Country Joe & the Fish appearing on 8/2/1968 and the Chambers Brothers appearing on 8/3/1968, both shows supported by Country Weather and held at the Sound Factory in Sacramento, CA. 

 Art by San Andreas Fault (Tad Hunter), medium glossy-coated index stock poster is in excellent (B+) condition; aside from a set of tiny pin holes (all four corners), a few stray soft handling dings/thin stress bends here and there and a couple of tiny diagonal corner-tip bends, it is a VERY nice-looking example of this highly psychedelic Sound Factory poster from mid-1968.
