Promoting Grateful Dead concerts w/opening bands Quick Silver Messenger Service at the Avalon Ballroom in San Francisco, CA on Jan. 27-28, 1967. Superb graphic w/pin hole in each corner, smudge at 3 o'clock in red field, corner bumps and edge wear. Small light brown stain on verso at bottom left not affecting front view. Fine.
