Superman (Silver Age)
From DC Database
Silver Age Superman refers to the various incarnations of the character who mostly operated from the mid 1950s to the mid 1970s
Like the previous "Golden Age" this era was populated with many different incarnations of the Superman character. Its most noted version was the infinitely powered Earth-One version whose power levels where so incredible that he practically had no limits!
- See: Kal-El (Earth-One)
It was also during this era that the distinction of Kal-L (the Earth-Two Superman) was formally made and the two primary incarnations of the character specifically met. Kal-El's life on Krypton was formally established that he was at least three years old and understood Kryptonese before the explosion that destroyed his home planet. The self discovery of the Golden Age version was eliminated as Superman already knew where he came from and why he was so different from everyone else.
Again like most of the alternate reality tales of the Golden Age, many of these other Silver Age incarnations were usually only referred to one time and never again and to even further discount them many of these tales were specifically called "imaginary tales" to prevent confusion with the main version of the Superman character.
