Original 1st printing (fine dot screen in the skull logo at top center with extensive ghosting on the reverse side) 11&1/2 x 20" concert poster for Cold Blood appearing with Cat Mother, Gold, the Getto and Fox in a Free Clinic benefit sponsored by the Hells Angels Motorcycle Club, held at Longshoreman's Hall in San Francisco, CA on 6/23/1971.
 
 Art by Randy Tuten, image ("Clap Clinic Benefit") is featured in the Art of Rock book on page 335 (plate 4.13). *the one pictured in the book is an untrimmed proof

 Medium flat index stock poster is in excellent (B+) condition; there are a few ULTRA-thin hairline stress creases scattered across the upper edge of "Hells Angels", along with a tiny thin diagonal bend in the upper left corner tip, a few soft pinch dings along the top margin, a couple of soft horizontal roll bends in the lower left/right margins and a couple of minor ink scrapes/scratches on the reverse side, otherwise it is an absolutely STUNNING example of the semi-elusive 1st printing of this popular Randy Tuten image.
