Superman Old Man Kal Collection
The reference to Kal in the Superman Old Man Kal Collection refers to the name Superman was given by his biological parents, Jor-El and Lara on the planet, Krypton, where he was born: Kal-L. On Krypton, his name signifies that he is Kal of the House of El. El means Child and Kal means star. Thus the name Kal-El means Child of the Stars. The first mention of the name Kal-L (note that there was no E before the letter L) came in the a newspaper strip published on January 17, 1939.
In this Superman Old Man Kal Collection we see a retired Superman (some grey in his hair and wrinkles on his face) from Earth 22 coming out of retirement to fight evil as part of the 52 universe Superman army.
