Original 1st printing 8&1/2 x 11" concert flyer for the P.H. Phactor Jug Band appearing at the Matrix in San Francisco, CA from 11/7-11/1967.
Artist unknown/not credited, thin buff index stock flyer is in SUPERB near mint (A-) condition; aside from a tiny thin diagonal bend in the top left corner tip, a whisper of handling and a tiny edge ding or two, it is an unbeatable example of this late-'67 Matrix flyer.
