Officially licensed 2008 printing (Rhino Entertainment stamp on the reverse) 30 x 42" oversized lithograph print of a concert poster for Quicksilver Messenger Service appearing with Mount Rushmore from 6/29-30/1967 and Big Brother and the Holding Company (featuring Janis Joplin) appearing with Blue Cheer from 7/1-2/1967, all shows held at the Avalon Ballroom in San Francisco, CA.
 
 Art by (and SIGNED and numbered 5/5 "dedication print" (A/P) in pencil by) Victor Moscoso, image is # 68 in the Family Dog/Avalon series. 
 
 Extra-thick oak-tag vellum stock lithograph is in very good to excellent (B/B+ to B+) condition; there are a series of semi-pronounced creases scattered up and down the left/right margins and a soft handling bend or two hiding within the image area, otherwise it is a very sharp example of this oversized Avalon lithograph with an incredibly hard-to-read Moscoso design and an eye-searing color scheme.
