Original 1st printing 13&7/8 x 21" concert poster for rock & roll pioneers Bo Diddley and Big Joe Williams appearing with Big Brother & the Holding Company (featuring Janis Joplin, 7/4-6) and Quicksilver Messenger Service (7/7-9) at the Fillmore Auditorium in San Francisco, CA from 7/4-9/1967.
Art by (and SIGNED in black flair pen by) Bonnie MacLean, image is # 71 in the Bill Graham/Fillmore series.
Medium-thick flat index stock poster is in excellent (B+) condition; aside from a series of very well-camouflaged horizontal thin stress/impact creases running vertically down the left center of the image (it can really only be seen on the reverse side), it is a SUPERB-looking example of this somewhat strange-looking mid-1967 Fillmore image with a nice Bonnie MacLean signature.
