Batman, Son Of Krypton

Here's a great World's Finest piece from the same era as when Julie Schwartz & Carmine Infantino were bringing Batman into his 'New Look' period, and wiping away all that Zebra Batman / Bat Hound / Batman on alien worlds nonsense.
Just a year or so earlier, the idea that The Caped Crusader might actually have come from Krypton would've been explained away by Red Kryptonite, or a practical joke Supes was playing on his pal for no apparent reason, and in fact, you read this whole story on tenterhooks waiting for just that to happen.
But no. In line with the comparative seriousness going on in Bats' own book at the time, writer Edmond Hamilton plays this one dead straight, and the rage Supes feels at the 'truth' of Krypton's destruction is genuine.
I always knew Curt Swan was great of course, but just now discovering how great Hamilton was too.

Superman & Batman: The Super-Foes From Planet X

Back to the Silver Age now, for one of those super silly World's Finest stories where Bats, Supes & Robin fight aliens. Y'know, one of those tales everybody says they hate, and that ruined the Darknight Detective for years, but that always raise a smile and that we all like really.
My personal Bronze Age was still full of reprints like this, and I had no problem slotting them right alongside more 'serious' fare, and enjoying them in the spirit they were intended.
After all, I didn't know the Silver Age was over and we were now in the Bronze Age. Nobody told me.
This one, The Super-Foes From Planet X, has always stuck with me, if only for the scene with the matchbox and the genius way Batman escapes the trap the alien's put them all into.
Go on, smile. You know you want to.
