Circulation figures remained close to a million copies per month after the debut issue, which outstripped even the circulation of news magazines such as "Time" during the period. The character was widely imitated by other comics publishers, with around 40 red-white-and-blue patriotic heroes debuting in 1941 alone. After the Simon and Kirby team moved to DC Comics in late 1941, having produced "Captain America Comics" through issue #10 (January 1942), Al Avison and Syd Shores became regular pencillers of the celebrated title, with one generally inking over the other. The character was featured in "All Winners Comics" #1–19 (Summer 1941 – Fall 1946), "Marvel Mystery Comics" #80–84 and #86–92, "USA Comics" #6–17 (Dec. 1942 – Fall 1945), and "All Select Comics" #1–10 (Fall 1943 – Summer 1946).
