Original 1st printing 13&7/8 x 19&5/8" concert poster for Quicksilver Messenger Service appearing with the James Cotton Blues Band, Ace of Cups and Congress of Wonders at the Continental Ballroom in Santa Clara, CA from 8/4-5/1967.
Art by Grasshopper, thin flat vellum stock poster is in near mint to excellent (A-/B+ to B+) condition; just a few VERY well-hidden handling dings/pin-prick surface scuffs hiding within the image area, a negligible edge/corner ding or two and a couple of light brown glue residue marks on the reverse, otherwise fine.
Nice-looking low-run 1967 Quicksilver poster from the (still in-use) Santa Clara venue (current home to Santa Clara Aquamaids Bingo!).
