Mike Sekowsky (1923-1989) was a prolific workman of the Silver Age of comics, notably co-creating the Justice League of America for DC in 1960, and having a run as writer/artist on Wonder Woman. But he began at Timely, drawing everything from Ziggy Pig and Silly Seal to The Human Torch and The Sub-Mariner. He had a rapid, distinctive style and racked up a large number of mostly unsigned credits over a couple of decades, making him possibly the most prolific penciler at Timely. During the Atlas era, Sekowsky drew stories for Apache Kid, Marvel Tales, My Own Romance, Crime Must Lose!, Black Rider, Adventures Into Terror, Mystic, Journey Into Unknown Worlds, Love Adventures, True Secrets, Men in Action, Strange Tales, Battle, Patsy and Her Pals, Crazy, and many more. Alongside this prolific 1950s output, Sekowsky did ghost work on daily strips including Sherlock Holmes and Flash Gordon. He shifted to animation work in the 1970s, designing characters for Hanna-Barbera cartoons, including Scooby Doo and Super Friends.
