In Action Comics #106 (January 1947), Clark is told he is a long-lost heir to an English barony. But what’s interesting (as a reader 70 years later) is the blurb in which it is revealed that Clark doesn’t even know he is not human. At this point in his history, Clark does not know anything about Krypton, Jor-El, or his alien origins! It will take a couple more years before he discovers the truth.
