In the 1980s Jaxon contributed historical comics to Fantagraphics' "Graphics Story Monthly" and a number of Kitchen Sink Press titles, including "BLAB!" and the 11-part, 126-page "Bulto… The Cosmic Slug," about a space creature's effect on the people of the ancient Southwest, which was serialized in "Death Rattle". Jackson did freelance work for Marvel Comics as a colorist from 1988 to 1991.
