Original 1st printing 8&1/2 x 11" benefit* concert flyer, "Peace Rock 3", a show featuring the Grateful Dead, Great Society (featuring Grace Slick), the Charlatans, Billy Moses Blues Bag and DJ Russ "the Moose" Syracuse appearing at Harmon Gym on the campus of the University of California in Berkeley, CA on 5/7/1966. (*Democratic Congressional Candidates Vietnam Study Group)

 Art by Fraser, medium-thick semi-gloss stock flyer is in good/decent (B to B/B-) condition; there is a decent-sized (1&1/8 x 1/2") half-moon-shaped chunk of paper missing from the bottom center margin, along with a series of staple holes/tiny drag tears and tape residue spots in the top center margin, a bit of light moisture staining along the right margin, a few light surface scuffs and pin-prick age spots scattered around the image area, light handling wear and a bit of semi-coherent pen scribble on the reverse (see photo), otherwise fine. 

 Conditional issues aside, it's still an INCREDIBLY uncommon early Grateful Dead item, the first example I have ever seen on this particular paper stock.
