Jay Kinney was part of the 1970s underground comix scene from the beginning. His work first appeared in Bijou Funnies in 1968, and he co-founded the satire of romance comics, Young Lust Comix, with Bill Griffith in 1970. He produced and edited several other publications, such as Occult Laff-Parade in 1973, Cover-up Lowdown with Paul Mavrides in 1977, and Anarchy Comics (1978-1987). He was editorial cartoonist for In These Times in 1979-80, editor of Co-Evolution Quarterly (1983-84) and publisher and editor-in-chief of the esoteric spiritual magazine Gnosis (1985-1999). Kinney and Mavrides designed the website for Infinite Matrix, an online science fiction magazine, and provided illustrations for the fiction at the site.
Kinney made a graphic contribution to 'ProJunior’ (Kitchen Sink Press, 1971), a one-shot comic book paying homage to Don Dohler's character ProJunior. He wrote a personal homage to Robert Crumb in Monte Beauchamp's book 'The Life and Times of R. Crumb. Comments From Contemporaries (St. Martin's Griffin, New York, 1998).
