Original 1st printing 15&1/2 x 23&1/8" event poster for "The End of the War", a Diggers-sponsored event held at the Straight Theater in San Francisco, CA on 11/5/1967.
Artist unknown, image is featured in the Art of Rock book on page 199 (plate 2.219).
Medium-thick flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a minor amount of handling wear, a couple of tiny corner tip creases and a whisper of surface wear, this example is just about as sharp/crisp as they come. The photo in the Art of Rock poster does NOT do this poster justice, the colors are way brighter/more saturated in person.
Interesting poster from a somewhat curious and very obscure event, check out this interview with former Diggers Judy Goldhaft and Peter Berg detailing the Living Theatre's participation:
