These are the complete (known) adventures of Jack Steel, Nazi Fighter and officer of the International Police Service, aka COMMANDER STEEL. With amazing strength and speed from his “Elixir Of Power,” Steel fights for the oppressed and battles the forces of evil in the pages of Grand Slam Comics (for a few issues Grand Slam Three Aces). Golden Age Superhero adventure at its best! It is possible that there are more adventures of COMMANDER STEEL; even very likely. Many issue of Grand Slam Comics are not indexed.
