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

 Art by Stanley Mouse, image ("Dance") is # 96 in the Family Dog/Avalon series.

 Medium flat index stock poster is in very good to excellent (B/B+ to B+) condition; there are pin holes in all four corners, along with a pair of soft diagonal bends in the upper left corner, a few light handling dings here and there and a couple of miniscule edge/corner-tip dings, it is a fine-looking example of this very pretty late-'67 Mouse image from the Avalon series.
