I was just reading in an article that Bruce Wayne & Selina Kyle had a relationship in their civilian guises prior to 1983 (Batman #355) when Selina, who is a known former criminal, inexplicably knows Bruce's identity as Batman. How she knew and where this goes is a long story, but I wanted to start off by asking, when, prior to 1983, did Bruce and Selina date? And when was Selina's identity as Catwoman revealed to Bruce/the world?
EDIT (04/13): Okay, that question has been answered: The 1950 issue Batman #62 revealed Catwoman's identity. BUT, Crisis put her identity back in the bottle, for both Bruce and everyone else. So my NEW question is, when (and it had to be pre-Hush, as he knew who she was then) did Bruce learn of Selina's identity AGAIN, and did the rest of the world learn it too?
