Victory Bonds is an AU version of the early career of Superman, Batman, etc. set immediately after WW2. It's got a lot of the L&C flavour in the interaction between Lois and Clark, but does the period aspects really well, and has a fun plot that draws on history but still has room for mad scientists etc.. There's one non-canon gay relationship amongst the secondary characters, but nothing anyone should find offensive, if you can live with that it's a very enjoyable story.
