Original 1st printing 14 x 20" concert/event poster for "Vietnam Summer", a benefit show featuring the Morning Glory, Indian Head Band, the New Salvation Army Banned, Hair, the Lighthouse and Grandmother Picket's Surprise at California Hall in San Francisco, CA on 9/15/1967. Art by D. Pallavicini/Kaleidoscope Studios, medium flat vellum stock poster is in good/decent (B to B/B-) condition; a light amount of moisture staining and light wear (slight fraying and a couple of small tears) in the top margin, a subtle drip stain that runs vertically from about 4" from the top right side, descending down to the "L" of "Lighthouse", a couple of ultra-light moisture stains in the borders and a whisper of handling wear, otherwise fine. Very cool mid-'67 Cal Hall benefit poster with and interesting design.
