Original 1st printing 15&1/2 x 23&1/8" concert poster for the 6/13/1975 Orange County Jam, held at the Anaheim Convention Center in Anaheim, CA and featuring Hot Tuna (Jorma Kaukonen and Jack Casady of Jefferson Airplane) appearing with John Mayall, Honk, the Sons of Champlin and Les Moore.

 Art by Rick Griffin, image is featured in the Art of Rock book on page 372 (plate 4.123).

 Medium-thick flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a couple of ultra-soft light surface smudges in the top border area, a few semi-pronounced pinch dings in the lower left corner, light handling (mostly along the top/right edges) and a whisper of surface wear, otherwise fine.

 Very charming mid-'70's Rick Griffin concert poster from an eclectic Southern California show.
