Chet Helms was manager of Big Brother and the Holding Company, which famously added Janis Joplin as its singer for a period. Helms formed Family Dog Productions, and began producing concerts at the Fillmore Auditorium alongside a young Bill Graham. Helms and Family Dog hired a group of young artists to design the graphics for their posters and handbills, which became the standard by which all psychedelic concert posters would be measured. Artwork by Rick Griffin. Item #1143.
