Original 1st printing 17&3/8 x 11&1/2" concert poster for "Peace Rock", a benefit (*for Congressional candidate Tom Storer) featuring performances by the New Tweedy Brothers and the San Andreas Fault Finders, held at California Hall in San Francisco, CA on 10/1/1966.
 
 Artist unknown/not credited, medium glossy-coated index stock poster is in good (B) condition; there are a series of tack/pin holes in the upper left/right corners and along the bottom margin (a couple of the holes have tiny drag tears), along with a thin vertical crease/bend going through the center of the image area, a couple of thin edge/corner-tip bends, a small dime-sized tape residue stain just to the right of the girl's foot, a hint of toning, a few well-camouflaged stress bends and minor handling creases here and there and a set of tape marks/light pulls on the reverse side, otherwise OK.
 
 VERY uncommon oddball 1966 California Hall benefit poster from a fairly obscure event.
