Original 1st printing 8&1/2 x 11" concert poster for the one and only Captain Beefheart (and His Magic Band) appearing with the Charlatans at the Avalon Ballroom in San Francisco, CA from 8/26-27/1966.
 
 Art by Stanley Mouse and Alton Kelley, image is # 23 in the Family Dog/Avalon series. (OHB-A in the Eric King guide)
 
 Thin flat stock flyer is in near mint to excellent (A- to A-/B+) condition; there is a VERY soft vertical bend going from the top center margin into the top  of the "f" of "Beefheart" and that's just about IT... an overall FANTASTIC example of this semi-early Mouse/Kelley Avalon flyer.
