Original first printing 14 &1/4x20" concert poster for The Quicksilver Messenger Service, The Miller Blues Band, and The Daily Flash, at the Avalon Ballroom in San Francisco, CA on 3/10-11/1967. 
 
Art by Victor Moscoso.
 
The poster has multiple tackholes on all four corners and single tackholes on the top and bottom.  There are two torn corners.  There is a tiny white streak in the black area near the bird.  There is a fold crease near the bottom corner and some edgewear throughout.  This poster was definitely hung up and diaplayed.
