The pulp, Super-Detective, with its adventure hero, Jim Anthony, started out as a competitor to Doc Savage. After 10 issues, the publisher turned Anthony into a hardboiled detective. This Flip Book, with a book on each side, explores both worlds. The front side is Legion of Robots, a Doc Savage style novel from the issue of November 1940, written by Victor Rousseau. The flipside has Murder's Migrants, a hardboiled story from March 1943, by the team of Robert Leslie Bellem and W.T. Ballard. Introductions that describe the behind-the-scenes story of Super-Detective are provided by, respectively, John McMahan and John Wooley.
