Original 1st printing 12&1/2 x 20&7/8" concert poster for the 5/10/1969 Pacific Pop Festival, a single-day event held at Pacific Memorial Stadium on the campus of the University of the Pacific in Stockton, CA. Design by Carson-Morris Studios, the event lists Santana, Cold Blood, the Sons of Champlin, Elvin Bishop, Sanpaku and Country Weather. Medium-thick flat vellum stock poster is in good (B to B/B-) condition; a couple of pin/tack holes in all four corners and in top/bottom center, a 3/4" tear in the top center, a semi-flattened horizontal center crease, a minor degree of handling wear, a bit of light edge/corner creasing and a couple of small tape marks on the reverse, otherwise a fine-looking example of this whimsical Rick Griffin-inspired design from a small regional CA event.
