Superman #21 (1943)

Ah, Superman #21 from 1943. A true gem in the world of comics. This issue featured not one, not two, but four different stories that will leave you on the edge of your seat.

First up is "The X-Alloy", where we see Superman teaming up with Perry White and Sgt. Casey to investigate a new metal that's causing quite a stir.

Next, we have "The Four Gangleaders", in which Superman, Lois Lane, Perry and Sgt. Casey work together to put a stop to some bad guys who are causing trouble in Metropolis.

In "The Robber Knight", our favorite characters once again band together to catch a thief who's been stealing from the wealthy citizens of town.

Last but not least, "The Ghost of Superman" will give you goosebumps as Lois Lane experiences some eerie encounters with a supposed ghost of the Man of Steel himself.
