Original 1st printing 14 x 21" concert poster for the Electric Flag (featuring Mike Bloomfield and Buddy Miles) appearing with Moby Grape (8/8-9), the Steve Miller Band (8/10-13) and the South Side Sound System (featuring Charlie Musselwhite) at the Fillmore Auditorium in San Francisco, CA from 8/8-13/1967.

 

 Art by (and SIGNED in black pen by) Bonnie MacLean with a photo by Jim Marshall, image is # 77 in the Bill Graham/Fillmore series.

 

 Medium-thick flat stock poster is in BEAUTIFUL mint/near mint to near mint (A/A- to A-) condition; aside from a couple of ULTRA-tiny stress bends going around the outer margin area, it is a VERY sharp/crisp example of this early 1967 Fillmore poster with nice strong inking and a BOLD Bonnie MacLean signature.
