One thing I read about these which I couldn't verify was that, in the original first cartoon, Clark's line at the end of the first scene is, "Chief, don't you think that's a dangerous job for a woman?" On all the editions I have, it's just "dangerous job." I'd be curious to see if that's true.
Here's the Max Fleischer's Superman 1941-1942 (Warner Bros 2008) set I used for most of the video.
