Superman/Batman 50: World's Finest Dads
You know we need to get more stuff from the old lj mentioned here.
This is from Superman/Batman 50 where we discover that improbably Jor-El and Thomas Wayne met.
It's a 38 page book I've got twelve and 2/3's below the cut. Basically Thomas's entire Kryptonian adventure.
This is the trimmed page. The first panel is just Thomas thinking he heard Martha yelling from the car before he passed out.
There was actually an arc in the Superman comics where we see how his life would have turned out if he went to other planets. In that one when he went to Thanagar they manipulated his powers so his supersenses were enhanced at the expense of everything else so he could help create a police state.
As I said at the time, this was a kind of Silver Age-ish story. It's never going to be mentioned again so it doesn't change anything. All in all it's a good story.
