Original 1st printing 13&3/4 x 24&3/4" concert poster for Quicksilver Messenger Service appearing with the Chambers Brothers and Sandy Bull at the Fillmore Auditorium in San Francisco, CA from 4/7-9/1967.

 Art by Wes Wilson, image is # 58 in the Bill Graham/Fillmore series.

 Medium-thick flat index stock poster is in excellent (B+) condition; all four corners have minor creases/tiny bends and there are a couple of soft handling creases scattered around the outer margin area, a tiny thin scratch in the top center margin  and a couple of nearly-invisible fingerprint smudges hiding within the image area, otherwise it is a VERY nice-looking 1st printing example of this classic early-'67 Fillmore poster with a gorgeous Wes Wilson design.
