First appearing on a 1968 concert poster featuring Santana and Big Brother & the Holding Company at the Fillmore West, Rick Griffin's Heart and Torch design soon became one of his most famous. Ranking high on the recognition scale among Griffin fans, sharing top-three with the Flaming Eyeball [Jimi Hendrix] and Aoxomoxoa [Grateful Dead] posters, some say this particular artwork reflected his emerging Christian sensibilities projected on the defiantly secular San Francisco surroundings.
