A rare March 1966 Los Angeles Acid Test psychedelic concert poster designed by longtime Grateful Dead associate Owsley Stanley, affectionately known as “Bear.” The Dead played this show, along with folks like Tiny Tim and improv pioneer Del Close. This window card is short on color but long on history, design and charisma. Enthusiastically discussed by collector Pete Howard of PosterCentral.com (phone 805-540-0020, email pete@postercentral.com).
