Anyone wanting to see the masterful Max Fleischer studios treatment of Superman has, for years, been able to get a cheap copy, due to the shorts having fallen into the public domain. So why would you want to pick up yet another copy just because it's on Blu-ray?
Because the transfers are infinitely better, cleaner, and brighter. Not only have all the pops, pits, potholes and scratches been cleaned up so that the animation is pristine, but the scans of the master prints take in even more of the artwork.
We tested the new Blu-ray side-by-side with previous releases of the shorts. As an example, the short "Volcano" had an ever-present pit during the opening scenes; this has been removed. Additionally, what we didn't expect to see was more artwork that had been cut off from all four sides in previous releases. So you're quite literally getting more for your money with this purchase.
