Original 1st printing 8&1/2 x 11" concert flyer for the Daily Flash appearing with Country Joe & the Fish at the Avalon Ballroom in San Francisco, CA from 10/21-22/1966.
Art by Stanley Mouse and Alton Kelley, image is # 31 in the Family Dog/Avalon series (OHB-D in the Eric King Guide)- this is the corrected dates/2nd-state edition.
Thin flat stock flyer is in excellent (B+) condition; there are pin holes in all four corners and in the top center margin, along with a 1" diagonal bend in the upper left corner, a trace of edge toning, a very light amount of handling wear, a couple of soft vertical/diagonal bends in the left margin, a tiny nick and pressure crease in the bottom center margin and a tiny vertical black ink streak in the upper right margin, otherwise fine.
Really nice-looking example of this late-'66 Avalon flyer.
