Original 1st printing 14 x 20" concert poster for The Steve Miller Band appearing along with the Daily Flash on 6/1-2/1967 and with the Doors on 6/3-4/1967, all shows at the Avalon Ballroom in San Francisco, CA. Art by Victor Moscoso, image ("Two Heads") is # 64 in the Family Dog/Avalon series. Medium flat index stock poster is in very good (B/B+) condition; a series of tack/pin holes (all four corners, 2-3 tiny holes in each) with a bit of minor wear in the top/bottom left corners, light handling, a few stray tiny surface spots and a touch of subtle toning, otherwise fine. A fine-looking example of this classic 1st printing Moscoso Doors poster.
