for "boys' life" evans drew "space conquerors!" for the august 1953-march 1958 issues. during the 1960s, he was an assistant and ghost artist for george wunder on the comic strip "terry and the pirates". he did occasional work in comic books during this period, most notably for warren's "blazing combat" black and white magazine and "eerie", gold key's "the twilight zone" and "ripley's believe it or not!" during the 1970s, he contributed comics to the "national lampoon". he drew dc comics' war comics and mystery tales, and for marvel comics he did mystery-horror stories plus work on two issues of "super-villain team-up" featuring doctor doom and sub-mariner. al williamson passed "secret agent corrigan" on to evans in 1980, and the strip ended with his 1996 retirement. for several years before that, the strip, as with all story strips, was becoming less popular. as the strip's circulation dwindled, the syndicate was about to cancel it in 1991. originally, evans had been glad, and had taken on other work. then evans was lured back, because it turned out that the strip's popularity in european markets justified keeping it going for five more years.
