Especially back in the Golden Age, those big ol' ears on hos cowl constantly got in the way whenever the artist insisted on doing a close-up, and the poor letterers had to work around the doofy things!
Seriously, someone should do a PhD dissertation on how often Batman's "ears" got in the way back in the day...
They even interrupted other people's word balloons!!
Believe it or not, these are all from just 1 issue!! One story!!
Seriously, how would you have to work like that, having to try and squeeze your fine letters around those protruding ears?
Of course, it wasn't just that issue...
And in other stories, the ears even pierced the captions!!
Not to mention, the disrupted telepathic communications!! (No, seriously)
Seriously, if I were a letterer back in the day, I'd have asked to been assigned to a nice, safe Superman book. Anything but Batman and those ears!!
From Detective Comics #34 (1939) and #35-36 (1940)
