Original 1st printing 20&1/4 x 14&1/4" concert poster for the Chambers Brothers appearing with A.B. Skhy and Stillborn Time at the Sound Factory in Sacramento, CA from 7/19-20/1968. 

 Art by San Andreas Fault (Tad Hunter), medium glossy-coated index stock poster is in very good to excellent (B/B+ to B+) condition; there are a series of light circular surface indentation marks from a bit of (erased) pencil scribble on the reverse side, along with a few well-camouflaged thin stress bends and light handling creases scattered throughout the image/outer margin area and a bit of toning on the reverse, otherwise fine.

 Nice-looking example of this very colorful Sound  Factory poster from mid-1968.
