Original 1st printing 11&1/4 x 20&1/2" concert poster for Quicksilver Messenger Service appearing with the Congress of Wonders and the Charlatans at the Avalon Ballroom in San Francisco, CA from 12/15-17/1967.

 

 Art by Stanley Mouse (who also SIGNED the poster in black ink) with Alton Kelley, image ("Dance") is # 96 in the Family Dog/Avalon series.

 

 Medium flat index stock poster is in absolutely STUNNING mint/near mint to near mint (A/A- to A-) condition; a VERY crisp/sharp example of this very pretty late-'67 Avalon poster with a HUGE Mouse signature.
