Doomsday + 1  Doomsday + 1 was an American post-apocalyptic comic-book series published by Charlton Comics in the 1970s. It is best known as the first original, color-comics series by artist John Byrne, who would go on to become a major industry figure. Byrne had previously drawn three unrelated, anthological short stories for comics, as well as the first three issues of a Saturday-morning cartoon licensed comic book before co-creating this original series. "Doomsday + 1" originally ran six issues, cover-dated July 1975 – May 1976. Two years after its cancelation it was revived as an all-reprint series with issues #7–12 (June 1978 – May 1979), reprinting the contents of the first six issues. The series was created by writer Joe Gill and penciler-inker John Byrne for the small, Derby, Connecticut-based publisher Charlton Comics, under editor George Wildman. Byrne, who also served as letterer, used the pseudonym "Byrne Robotics" for issue #4–6 (reprinted as #10–12). The credits for issue #5 credit the artwork as "Art: Byrne Robotics with technical assistance from Patterson-75", a pseudonym for Bruce Patterson, who provided some degree of inking. Byrne drew the covers of issues #2–6, with the cover of issue #1 variously credited to Byrne and to Tom Sutton. Issues #7 and #11 featured re-colored reprints of Byrne covers, while issues #8–10 and #12 featured "new" covers created by blowing up panels of interior artwork from the stories. Stories ran 22 to 23 pages, with most issues also containing a two-page text backup – either a story featuring the main characters or a non-fiction featurette. The backup in issue #5 consisted of two comics pages, drawn by Steve Ditko, of "real world" paranormal vignettes. One additional 22-page story was produced by Gill and Byrne, but was not published in the original series. It appeared in two parts titled "There Will Be Time, Part One: Time-Slip" and "Part Two: The Man from Elsewhen" in publisher CPL/Gang Publications' Charlton-sponsored comic-book/fanzine hybrid "Charlton Bullseye" #4–5 (April & Sept. 1976). Sales of the 1978–79 reprint issues began strong, and editor Wildman assigned Tom Sutton to write and draw a 15-page story scheduled to run as issue #13.
