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 decent/used (B/B- to B-) condition; there is a moderate amount of creasing, along with staple/tack holes in all four corners and around the outer borders of the image area, a couple of fairly tattered/worn corner-tips (wedge tears/pulls), a pair of 3-4" diagonal creases along the upper right margin and a few stray edge nicks scattered around the outer margin area... definitely a bit on the used side, but still all there. 

 Uncommon early-'67 QMS poster concert featuring the original 5-piece lineup of the band.
