In fact, the story wasn't exactly the same as this of Chuck Dixon and Carlos Meglia; instead of taking place in the late 19th century, it happened today (ie in the 60’s), and Tarzan didn't appear. Young Kal El is adopted by a band of gorillas and becomes a Super wild man. I don’t remember who wrote the script, but I am certain it was drawn by the immortal Kurt Swann. It was before “Elseworlds” series came up, and the presentation used to read: “an imaginary story which may or may not happen”. Int the site, you came read some stories of that sort like “the death of Superman” for instance (
http://superman.nu/tales2/death/1/ ), or another which is famous where Lex Luthor is the son of Jorel, he is born on Krypton and sent earthward by his father in a rocket, to avoid him being killed when Krypton explodes (classical).
As a grown up, Lex becomes “Super Lex”. In this story, Super Lex fight for the good, and Clarck Kent, who’s a simple mortal is an evil scoundrel. It was also drawn by Curt Swann.
BTW, have you read the late “Red Son”? an elseworld story where Kal El’s rocket lands in USSR in 1938, and Superman grows up in Communist ideal. I think it’s also a remake of an imaginary story of the 60’s.
