Original 1st printing 11 x 21" concert poster for Buffalo Springfield (featuring Stephen Stills, Richie Furay and Neil Young) appearing with Hour Glass (featuring Duane and Gregg Allman) and the Collectors at the Fillmore Auditorium in San Francisco, CA from 12/21-23/1967.
 
 Art by Alton Kelley and Stanley Mouse, image is # 98 in the Bill Graham/Fillmore series. This is the type 2 version ("B. GRAHAM 67" scratched into the plate, OP-2 in the Eric King guide)
 
 Medium-thick flat index stock poster is in very good to excellent (B/B+ to B+) condition; there are tiny pin/staple holes in all four corners and in the ticket outlet area, along with a touch of edge toning, a few stray handling/edge dings here and there and a couple of light smudges/stains on the reverse, otherwise fine. 

KILLER late-'67 1st printing Fillmore poster with a great Kelley design and a fantastic lineup.
