Official promoter-issued 3rd printing (the second reprint, RP-5 in the Eric King guide) 13&1/4 x 24&1/4" concert poster for Jefferson Airplane, the Paul Butterfield Blues Band and Muddy Waters appearing together at the Fillmore Auditorium and Winterland in San Francisco, CA from 9/23-25 and from 9/30-10/2/1966. (*Winterland shows were canceled/moved back to the Fillmore)
 
 Art by Wes Wilson, image ("The Sound") is # 29 in the Bill Graham/Fillmore series.
 
 Medium-thick flat index stock poster is in near mint to excellent (A-/B+ to B+) condition; aside from a soft handling crease along the lower left margin/edge, a couple of soft bends in the upper left/right corner tips and a whisper of surface wear, this example is in absolutely FANTASTIC shape.

 As an added bonus, this one has been HAND-SIGNED (in silver ink by) Jefferson Airplane lead singer Grace Slick!
