About Four Teeners
*In September 1941, Ace Magazines launched their title Four Favorites. This was an anthology that included all of the company's superheroes. With the decline in popularity of superheroes, Four Favorites abandoned the genre with issue #27. Then, with issue #33 in February 1948, the title was renamed Crime Must Pay the Penalty, retaining the sequence numbering. The second issue of Crime Must Pay the Penalty published in June 1948 was numbered #2 rather than #34, and spun off as a new title, meanwhile Four Teeners issue #34 appeared, which was the end of the run started by Four Favorites.
