Richard Alden Griffin (June 18, 1944 - August 18, 1991) was an American artist and one of the leading designers of psychedelic posters in the 1960s. As a contributor to the underground comix movement, his work appeared regularly in Zap Comix. Griffin was closely identified with the Grateful Dead, designing some of their best known posters and record jackets. His work within the surfing subculture included both film posters and his comic strip, Murphy.
Griffin was born near Palos Verdes amidst the surfing culture of southern California. Griffin biographer Tim Stephenson notes:
He traveled with Ida on a Mexican surfing trip and later planned a move to San Francisco after seeing the psychedelic rock posters designed by Stanley Mouse and Alton Kelley. In late 1966, the couple arrived in San Francisco, where they first lived in their van before moving to Elsie Street in the Bernal Heights district. In the mid-1960s, he participated in Ken Kesey's Acid Tests. His first art exhibition was for the Jook Savages, celebrating the one-year anniversary of the Psychedelic Shop on Haight Street. Organizers for the Human Be-In saw his work and asked him to design a poster for their January 1967 event. Chet Helms was also impressed by Griffin's work and asked him to design posters for the Family Dog dance concerts at the Avalon Ballroom, which led Griffin to create concert posters for the Charlatans. In 1967, Griffin, Kelley, Mouse, Victor Moscoso and Wes Wilson teamed as the founders of Berkeley Bonaparte, a company that created and marketed psychedelic posters. Griffin returned to Southern California in 1969, eventually settling in San Clemente.
Griffin adopted Christianity in November 1970, which led to fundamental changes in his lifestyle and in the style and content of his art. His 1973 painting Sail on Sailor for the band Mustard Seed Faith is an example of his fine art painting from this period. His most significant 1970s project was the creation of hundreds of paintings and drawings for The Gospel of John, published by the Christian record label Maranatha! Music. He also produced much album art for Maranatha! during the 1970s and 1980s.
