There’s the truly retro Batman of the Golden Age, there’s the dangerous Batman, the goofy Batman and, of course, The Dark Knight. For my money, if I were to invest in Batman, I’d go with the campy Batman of the ’60s along with anything else that places Batman in a more offbeat light. Looking over what is currently on bid at eBay, I’d go for Batman, #69, from February, 1952, with cover art by Win Mortimer. You can bid for it here.
