Original 2nd printing, 14 x 19 & 3/4" concert poster for The Mindbenders and the Chocolate Watchband at the Fillmore Auditorium in San Francisco, CA on 7/8-9/1966. 
 
Art by Wes Wilson, image is #16 in the Bill Graham/Fillmore series. 
 
The poster is in excellent vintage condition.  The poster has the measurements written on the back (doesn't show through.)  also small corner bends.  Otherwise very nice.
