Original 1st printing 14 x 20" concert poster for the Chambers Brothers appearing with Love (featuring Arthur Lee) and (not listed) a "Special Fantastic Boss Hit-Bound Group", which turned out to be (according to the show attendee) the Chicago (Transit Authority) at the Santa Barbara (CA) Bowl (later moved to the Earl Warren Showgrounds, as noted in pencil on the reverse) on 7/27/1968. Design by Bob Masse (uncredited)/Boom! Graphics, medium-thick flat index stock poster is in excellent (B+) condition; aside from a small 1" piece of browned tape in the right center margin, a tiny stain in the top margin, a light amount of surface/handling wear and a few tiny edge dings, it's a very sharp example of a HIGHLY unusual/oddball Southern California poster with a really cool retro-style design ("Those Cool Chevvies"). Neato!
