Copyright 1944 by Comic Magazines.
Writer credit revised from Joe Devlin to ? by Craig Delich 2013-4-6. Devlin did not write this strip according to the Who's Who. Artist correction from Joe (who did not exist) to John Devlin also made by Craig Delich. Both writing and art credits subsequently revised to Bernard Dibble, who did this strip from 1943 onward.
Art was originally credited to Paul Gustavson, but this is Leav. He has large hands and many lively faces, some panels without backgrounds, and a special way of running with high lifted legs. Compare with his signed story in Wanted Comics #52. He is credited on this feature by Jerry Bails' Who's Who on both pencils and ink. Jim Amash, in the Quality Companion, verifies that Gustavson wrote this feature through Police #22, then picked up again with #37. The intervening writer is unknown for this story.
