In 1969 Shelton and three friends from Texas founded Rip Off Press in San Francisco, which took over publication of all subsequent Freak Brothers comics.[4] The first compilation of their adventures, The Collected Adventures of the Fabulous Furry Freak Brothers, had its first printing in 1971 and has been continually in print ever since. In addition to underground and college weekly newspapers, new adventures appeared in magazines such as Playboy, High Times, and Rip Off Comix; these too were collected in comic book form. Shelton continued to write and draw the series until 1992, in collaboration with Dave Sheridan (1974–1982, his death) and Paul Mavrides (1978-1992).
