Although Pinnacle didn't last much beyond 1969 as a small, successful rock concert production company, it engaged highly talented artists to design the early posters: John Van Hammersveld, Rick Griffin and Victor Moscoso. In fact, Griffin's cartoon panels on an early Pinnacle poster series collaboration with Moscoso for Janis Joplin, Big Brother and B.B. King concerts introduced the two graphic artists to a second career with Zap Comics. Pinnacle's concerts were usually held at the Shrine Auditorium in L.A. but moved next door to the Exhibition Hall because, as the story goes, the Shriners failed to appreciate the delicate artistic value of tastefully presented female nudity in a Thomas Edison Lights light show.
