Superman #58 1991

Superman #58 (1949) features three distinct stories. It introduces Tiny Trix, a criminal who manipulates public opinion, and explores Lois Lane's attempts to redirect her affections towards Clark Kent. The issue is particularly notable for "The Case of the Second Superman," featuring Regor, a hero from the planet Uuz. Crucially for collectors, this comic marks the very first mention of the iconic "Fortress of Solitude," albeit as a cave hideaway.
