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 pen by) Bonnie MacLean, image is # 71 in the Bill Graham/Fillmore series.

 

 Medium-thick flat index stock poster is in FANTASTIC mint/near mint to near mint (A/A- to A-) condition; maybe there is a stray handling/surface ding or two hiding somewhere (I can't really see anything), but overall it is a VERY crisp/clean example of this odd-looking mid-1967 Fillmore image with a nice Bonnie MacLean signature.
