Original 1st printing 15&1/4 x 22&1/2" concert/event poster, held at the Finnish Brotherhood Hall in Berkeley, CA on 10/15/1966, featuring music by the Second Coming and a light show by Kaleidoscopic Infinity Projections. Art by Katy Smith, medium-thick vellum stock poster is in very good to excellent (B/B+ to B+) condition; a minor amount of corner wear (a few tiny pin holes, small bends and handling dings), a light amount of toning, a few subtle surface smudges and tiny stains and a few scattered stress/pinch bends, otherwise fine. Very cool-looking op-art style psychedelic poster from Berkeley.
