He went on to an atypically long, 10-year run on that humor series, from issues #18–93 (June 1949 – Nov. 1959), most of them published by Marvel's 1950s predecessor, Atlas Comics. DeCarlo and Lee also took over the "My Friend Irma" comic strip, spun off from the hit Marie Wilson radio comedy. For a decade, DeCarlo wrote and drew the slapsticky adventures of Millie Collins, her redheaded friendly nemesis Chili Storm and the rest of the cast. He also contributed the short-lived "Sherry the Showgirl" and "Showgirls" for Atlas. In 1960, he and Atlas editor-in-chief Stan Lee co-created the short-lived syndicated comic strip "Willie Lumpkin", about a suburban mail carrier, for the Chicago-based Publishers Syndicate. A version of the character later appeared as a long-running minor supporting character in Lee's later co-creation, the Marvel Comics series "Fantastic Four".
