The Bat-squint runs in the Bat-family. Still looking for more animated GIFs of Batman squinting as detailed in my earlier post.
The Batman, Batman: The Brave and the Bold and Batman Beyond are still unrepresented, as are any of the direct-to-DVD movies save for Under the Red hood. Can anybody help provide one?
Did the Bat-squint show up anywhere prior to Batman: The Animated Series in the 90s?
