SUPER-DETECTIVE began in October 1940, published by Trojan, which had earlier published SUPER-DETECTIVE STORIES in 1934 and 1935.  Initially, SUPER-DETECTIVE was a hero pulp, featuring Doc Savage wannabe Jim Anthony.  The Jim Anthony series ran for 25 stories, from "Dealer In Death" in the October 1940 issue to "Pipeline to Murder" in the October 1943 issue.  Though by-lined John Grange, the Jim Anthony series was apparantly written by Robert Leslie Bellem in collaboration with W.T. Ballard.  Although the Jim Anthony series ended in October 1943, SUPER-DETECTIVE continued on until the October 1950 issue.  Later issues featured a small comics section, perhaps trying to gain readership from the growing comics audience.  The cover to the February 1950 issue is by George Rozen, better known for his Shadow covers, but as shown, Rozen could do spicy covers with the best of 'em.
