The Matrix, San Francisco, CA 8/11 - 9/5/70

This handbill looks very similar to many of David Singer’s posters for the Bill Graham series, but it is designed and signed by M.T. Behrens. Here, Charley Musselwhite, Harvey Mandel, Big Brother and the Holding Company, Siegel-Schwall Blues Band, and Lovecraft performed at various points from August 11 until September 5.

The original handbill was printed on white stock and measures approximately 5¾” x 8½”.
