Original 1st printing 22&3/4 x 28&1/2" concert poster for "Summer Thing", a show held at the Santa Cruz County Fairgrounds in Watsonville, CA on 6/16/1968. Acts listed include: the Chambers Brothers, Hourglass (featuring Duane and Gregg Allman) and Buddha and the Boogie. 

 Designer unknown/not credited, medium-thick flat vellum stock poster is in excellent (B+) condition; the only real issues with this poster are a fairly light amount of handling wear (a few VERY soft bends and pinch dings scattered throughout the image area), a tiny stray edge ding or two and a few light smudges in the corners, but overall it is in GREAT shape... a really sharp-looking specimen of this HIGHLY obscure '68 piece from Santa Cruz. EXTREMELY uncommon Allman Brothers-related item.
