Officially licensed 2008 printing (Rhino Entertainment stamp on the reverse) 27&1/8 x 37&1/2" oversized lithograph print of a concert poster for the 13th Floor Elevators (featuring Roky Erickson) appearing with Quicksilver Messenger Service at the Avalon Ballroom in San Francisco, CA from 9/3-10/1/1966.
 
 Art by (and SIGNED and numbered A/P (artist's proof) 31/50 in pencil by) Stanley Mouse and Alton Kelley, image ("Zebra Man") is # 28 in the Family Dog/Avalon series. 
 
 Extra-thick oak-tag vellum stock lithograph is in excellent (B+) condition; there is a soft diagonal bend in the upper right corner, rough/hand-cut edges (as issued), a few light creases/surface smudges and a couple of VERY light/nearly-invisible tape pulls scattered along the outer margin area, otherwise it is a very sharp/extra-bright example of this MASSIVE ARTIST-SIGNED edition of the perennially-popular "Zebra Man" image.
