Original 3rd printing, 14 x 19 & 3/4" concert poster for The Association, Quicksilver Messenger Service, Grass Roots and Sopwith Camel at the Fillmore Auditorium in San Francisco, CA on 7/22-23/1966. 
 
Art by Wes Wilson, image is #18 in the Bill Graham/Fillmore series. 
 
The poster is in excellent condition.  Just a tiny bit of edgewear, and the number 95 written on the back.  Otherwise very nice.
