Original 1st printing 19 x 28" concert/event poster for the 6/3-4/1967 KFRC Fantasy Fair and Magic Mountain Music Festival, held at Mount Tamalpais Amphitheater in Marin, CA.
Two-day event (2 weeks before Monterey Pop) poster lists performances by the Miracles, the Blues Magoos, the Byrds, Wilson Pickett, the Seeds, the Doors, Jefferson Airplane, Country Joe & the Fish, Grass Roots, Tim Hardin, Mojo Men, Moby Grape, the Sparrow, the Loading Zone and Every Mother's Son. (*not all of the acts listed actually played, and there were several bands not listed on the poster that did appear- Captain Beefheart and the Magic Band, for one)
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 near mint to excellent (A-/B+ to B+) condition; aside from a couple of insignificant soft corner/edge dings (handling bends) scattered around the outer margin area and a couple of extra-thin horizontal creases traversing the word "Magic", this example is VERY sharp overall.
ULTRA-COOL looking oversized Stanley Mouse poster from one of the earliest "hippie" music festivals. Check out some great photos from the event HERE;
