Original 1st printing 8&1/2 x 11" concert flyer for Quicksilver Messenger Service appearing with Big Brother & the Holding Company (featuring Janis Joplin), the Loving Impulse, the S.F. Earthquake Dancers and the Congress of Wonders at Winterland in San Francisco, CA from 12/16-17/1966.
 
 Design by Gut (Allen Turk), image is featured in the Art of Rock on page 194 (plate 2.207).
 
 Thin flat stock flyer is in near mint (A- to A-/B+) condition; really nothing more than a few stray soft handling dings here and there and that's pretty much all there is to speak of... a pretty clean/unblemished example of this whimsical late-'66 BBHC/QMS concert artifact from Winterland.
