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 excellent (B+) condition; there is a tiny hard pinch bend and nip tear in the bottom center margin, along with a few VERY well-camouflaged handling dings/tiny thin stress creases/pin-prick surface indentations hiding within the image area and a couple of tiny stress creases scattered around the outer margin 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!).
