Original 1st printing 19 x 28" concert/event poster for the KFRC Magic Mountain Festival, held at Mount Tamalpais Outdoor Amphitheater in Marin County, CA from 6/3-4/1967. Bands/acts listed include: Jefferson Airplane, the Doors, the Byrds, the Seeds, Miracles, Wilson Pickett, Tim Hardin, Sparrow, Country Joe & the Fish, Mojo Men, Blues Magoos, Moby Grape, Loading Zone, Every Mother's Son and the Grass Roots (there were some lineup changes, including the addition of Captain Beefheart & the Magic Band (with Ry Cooder), Blackburn and Snow and several other acts) 

 Art by Stanley Mouse, image is featured in the Art of Rock on page 227 (plate 2.319).

 Medium-thick flat index stock poster is in good to very good (B to B/B+) condition; there are tack holes and creases/tiny bends in all four corners, a bit of minor creasing/light handling and a few tiny dings scattered around the outer margin area, a few soft pinch bends, fingerprint smudges and tiny stress creases scattered throughout the image area, a couple of hard creases along the top left margin/corner, a bit of light toning and a series of tape pulls on the reverse, otherwise fine. Very presentable example of this very gothic-looking Stanley Mouse poster from 1967.
