I guess I should add the current Blu-ray release to the list. (But beware ... it gets the kryptonite logos):

Max Fleischers Superman - Collector's Edition [Blu-ray]

by Gaiam (released 2012)

I don't have access to this one for matching pictures. (Can someone PM me his picture links to include here?) Until then, let these reviews suffice:

You can't blame Gaiam for trying with this new set, especially since Warner seems intent on sitting on its corporate hands and never spending the time and money to properly release the Fleischer Superman cartoons in high definition. But the problem with a PD release is—well, it's a PD release, which means the label wants to protect their handiwork (read: logos AKA bugs) and the source elements are more often than not completely inadequate for a real high definition presentation. That's sadly the case with this release.

Customer Reviews (multiple reviewers)

CAREFUL BUYING THIS...IT'S NOT FROM WARNER BROS.!
But here's the big, "BIG", problem with this set, the sound sync is off (only milliseconds for the first episode, but the next episode, The Mechanical Monsters, part way in when Lois and Clark are talking, the sound is so far off that it sounds like Lois is talking like Clark, as her lips are moving to Clark's spoken line).
First of all, each frame has a logo imbedded on the corner which is unacceptable. Second, this is not Blu-Ray quality image! It is full of artifacts and pixelized. It is just a blown up version of a smaller digitized edition of these cartoons.
It sucks Kryptonite, because if it wasn't for the sound sync issues, I'd actually prefer it to the Warner DVD's (even with the detail issues and the watermark in the lower right of the screen) because of the Blu-ray's vibrant colours, removal of the consistent print debris that plague every frame of the Warner DVD's and attempted sound enhancement which make the Warner DVD's sound flat by comparison.
