Psychedelic poster advertising a concert for Big Brother and the Holding Company and Pink Floyd. The event details are incorporated into the poster's design which is printed in dark purple-pink, a pale brown-yellow, and black and white, and features three women surrounded by Gothic arches. The lettering, which is printed in purple, is hand-drawn and arranged in the spaces between the arches, reads, 'Bill Graham presents in San Francisco Big Brother and the Holding Company, Richie Havens, Pink Floyd, Nov. 2-3-4 Fillmore, Thurs, Fri: Sat. Winterland, Lights by Glenn McKay's Head Lights'. Other motifs, which include ghostly faces and an eagle, fill other areas, and the overall imagery evokes a Medieval ambience.
