Other St. John comic books included the first movie-comedian tie-in series, "Abbott and Costello Comics"; one of the first proto-graphic novels, the 25-cent "picture novel" "It Rhymes with Lust" (1950); and a five-issue series (Sept. 1953 – Oct. 1954), appearing under three titles, that introduced the enduring Kubert prehistoric hero Tor. In 1953, St. John took over a number of Ziff Davis comics titles, including the romance comics "Cinderella Love" and "Romantic Love", the Western comic "Kid Cowboy", and the jungle adventure title "Wild Boy of the Congo".
