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, medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are staple holes in the upper left and right corners, with a pair of tiny wedge pull holes above the "on" of Cotton", along with a soft handling crease/tiny edge ding or two hiding within the image area, otherwise fine.
 
 Nice-looking low-run 1967 Quicksilver poster from the (still in-use) Santa Clara venue (current home to Santa Clara Aquamaids Bingo!).
