Original 1st printing 14 x 22" 1973 poster for the Grateful Dead, featuring the laughing raven from the "Wake of the Flood" album. Art by Rick Griffin, poster was printed/distributed by the California Graphics Exchange (Rick's poster company) in the early '70's through the C.G.E. "Cat-A-Log". Medium-thick vellum stock poster is in near mint (A-/B+) condition; only a couple of VERY small pinch dings along the right hand margin, otherwise this is a really sharp/crisp almost-mint example of one of the harder-to-find posters from the California Graphics Exchange series.
