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 tack holes in the upper left/right and lower right corners, along a small 1/4" tear in the upper left margin, a series of VERY light pinch dings/light creases scattered around the outer margin area, a couple of tiny red pin-prick ink spots in the top center margin and a couple of tiny corner tip bends, otherwise fine. 

 Very nice-looking example of this whimsical late-'66 Mouse/Kelley Avalon poster with a totally solid pass of black ink (no inking issues as many of them have).
