Original 1st printing (Berkeley Free Press) 13&1/8 x 21&3/4" concert/event poster for the Port Chicago Vigil Benefit, a show held at California Hall in San Francisco, CA on 2/19/1967, featuring appearances by Country Joe & the Fish, Steve Miller Band, San Francisco Mime Troupe and Robert Baker.
Art by Stanley Mouse, image is featured in the Art of Rock book on page 173 (plate 2.137).
Medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are a set of staple holes (all four corners), a series of light handling dings along the bottom border, a few stray pin-prick surface stains and soft creases scattered around the outer margin area and a tiny red ink mark in the upper left margin, otherwise fine.
GREAT-looking example of this somewhat uncommon 1967 Mouse image from the Art of Rock book.
