Dances With Bats
So here's what I learned from the Bill Finger/Sheldon Moldoff story in Giant Batman Annual #1:
When you're Silver Age Batman and you find a piece of three hundred year-old Native American pottery in your sprawling anti-crime basement, you don't just head down to your local library to find out more about where it came from.
No, you take it to someone who can send you back in time. And for what follows... there are no words.
Yes, for the record, that's Batman terrifying them with "Batarang Magic."
