Officially licensed 2008 printing (Rhino Entertainment stamp on the reverse) 37&1/2 x 18&7/8" oversized lithograph print of a concert poster for Big Brother & the Holding Company (featuring Janis Joplin) appearing with Oxford Circle on 8/5/1966 and Bo Diddley appearing with the Sons of Adam on 8/6/1966, both shows held at the Avalon Ballroom in San Francisco, CA.
 
 Art by (and SIGNED and numbered 394/500 in pencil by) Stanley Mouse and Alton Kelley, image ("Dollar Bill") is # 19 in the Family Dog/Avalon series. 
 
 Extra-thick oak-tag vellum stock lithograph is in good to very good (B to B/B+) condition; there are rough/hand-cut edges (as issued), along with a fairly prominent vertical bend that extends from the top left margin, going through the left side of the image down to just beneath the bottom "5", but other than that it is a pretty nice example of this extra-large DOUBLE-ARTIST-SIGNED edition of the classic "Dollar Bill" image.
