Alton Kelley, 67, who created the psychedelic style of posters and other art associated with the 1960s San Francisco rock scene, has died.

He died Sunday of complications from osteoporosis at his Petaluma, Calif., home, said his publicist.

The artwork that Mr. Kelley and his lifelong collaborator, Stanley Mouse, churned out included dozens of classic rock posters and album covers for the Grateful Dead, Journey, Steve Miller, Jimi Hendrix and the Beatles.
