The subject matter ranged from war to science fiction to jungle adventure, all with plenty of slam-bang action packed into each story. Tiger Girl and Captain Fight were two of the recurring characters who appeared over several issues. (Similarly, Wings featured a character called Captain Wings. Not terribly original, but.... )
Popular artists whose work appeared in this title included Matt Baker; George Tuska; Will Eisner (primarily the first several issues, probably when his studio was still providing the content); and Jack Kamen.
