Original 1st printing 13&3/4 x 20" concert poster for the Daily Flash appearing with Quicksilver Messenger Service and Country Joe & the Fish (Sat. only) at the Avalon Ballroom in San Francisco, CA from 11/18-19/1966.

 Art by Stanley Mouse and Alton Kelley, image is # 35 in the Family Dog/Avalon series.

 Medium flat vellum stock poster is in very good to excellent (B/B+ to B+) condition; there are tiny staple holes in the upper left/right corners, along with tack holes in the top/bottom center margins, a 3" diagonal bend in the upper right margin/corner, a couple of VERY thin vertical harline bends above "Sat.", a dark fingerprint ink smudge (possibly from Frank Westlake) on "19", a few soft handling dings hiding within the image area and a tiny pressure crease along the upper left margin, otherwise fine. 

Very nice-looking example of this whimsical late-'66 Mouse/Kelley Avalon poster.
