Original 1st printing (fine dot screen in the skull logo at top center) 13 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 (and SIGNED in pencil by) Randy Tuten , (full-color poster) image ("Clap Clinic Benefit") is featured in the Art of Rock book on page 335 (plate 4.13). This is a test proof edition without the red pass of ink that is on the final version.

 Medium flat index stock poster is in near mint (A- to A-/B+) condition; aside from a few ultra-soft handling dings hiding within the image area and a thin horizontal print anomaly going across the "lls" of "Hells" it is a fairly clean ARTIST-SIGNED example of this evocative 1971 Randy Tuten HAMC image.
