The popularity of Raymond's Flash Gordon Sunday strip meant a daily strip was also introduced. This strip was drawn by Austin Briggs and ran from 1941 to 1944. After Raymond left Flash Gordon in 1944 to join the US Marines, the daily strip was cancelled and Briggs took over the Sunday strip. Although Raymond wanted to return to drawing Flash Gordon after the war's end, King Features did not want to remove Briggs from his position. To conciliate Raymond, King Features allowed him to create a new strip, Rip Kirby. After Briggs left the Sunday strip in 1948, he was succeeded by former comic book artist Mac Raboy, who drew the strip until his death in 1967. In 1951, King Features created a new daily Flash Gordon strip. This strip was drawn by Dan Barry. Barry was assisted during his tenure by Harvey Kurtzman and Harry Harrison, who both wrote scripts for the strip. Barry also had several artists who aided him with Flash Gordon's illustrations, including Frank Frazetta, Al Williamson, Bob Fujitani, Jack Davis, Sy Barry, Fred Kida and Emil Gershwin. When Barry left the strip in 1990, various artists and writers worked on Flash Gordon. The daily strip was ended in 1993. The final artist to work on the Flash Gordon Sunday strip was Jim Keefe. Keefe was occasionally assisted on the strip by other artists, including Williamson, John Romita Sr. and Joe Kubert. King Features ended the Flash Gordon newspaper strip in 2003, although re-runs of Keefe's strip still appear in a few US newspapers.
