Anyway, you can probably tell by today's panels that editor Julie Schwartz was re-vamping the character, getting rid of the aliens, and just making much-needed improvements. The yellow oval under the chest emblem isn't a huge costume change, but it was a clear signal as to whether you were reading a pre-change or post-change Batman story back in the day.

Hey! It's time for Fun with Out of Context Dialogue! (tm!):

That's right, kids. Foreign people are "odd." Be ever vigilant!
See you tomorrow!
