Original 1st printing 14 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 good (B) condition; there are tack holes in all the top center margin and in the upper left/right corners (middle tack hole has a small crescent-shaped tear), there is a small wedge tear in the bottom left corner-tip and a small 1/2" diagonal wedge out of the bottom right corner tip, along with light handling wear/creasing, a few tiny pin-prick scuffs and spots hiding within the image area, a few tiny edge creases and a tiny nip tear in the upper right margin, otherwise fine.

 Very colorful original 1967 concert artifact from the (still in-use) Santa Clara venue (current home to Santa Clara Aquamaids Bingo!).
