Original 1st printing 14&1/4 x 19&7/8" concert poster for the Daily Flash appearing with Country Joe & the Fish at the Avalon Ballroom in San Francisco, CA on 10/21-22/1966.
Art by (and SIGNED in black flair pen by) Stanley Mouse, image is # 31 in the Family Dog/Avalon series. This is the incorrect dates/1st-state edition (OP-1).
Medium-thick flat vellum stock poster is in BEAUTIFUL near mint (A-) condition; aside from a couple of almost-invisible pinch bends hiding within the image area and a tiny thin vertical surface scratch in the ticket outlet strip, it is a really sharp-looking ARTIST-SIGNED example of this classic late-'66 Mouse/Kelley Avalon poster. You have to love the placement of the signature on this one.
