Original 1st printing 14 x 20" concert poster for Quicksilver Messenger Service appearing at the University of San Francisco Gymnasium on 4/15/1967. 

 Artist unknown, thin flat vellum stock poster is in near mint (A- to A-/B+) condition; really nothing more than a tiny edge ding or two scattered around the outer margin area and a negligible amount of handling wear (maybe a stray fingerprint or soft pinch ding or two) and that's IT... a VERY sharp/clean example overall.

 Great-looking early-'67 Quicksilver concert artifact featuring the original 5-member lineup of the band.
