Hmmmm.
A few years ago, perhaps the 60th or 65th anniversary, I ran across a thread similar to this one, and viewed it as a challenge to get a copy.
Took me three tries, but I DID get a copy. From Canada.
It took me three tries, the first two the DVD was confiscated by U.S. Customs, a branch of the US government and unconstitutional censorship, IMHO.
The third try, I had my stepdaughter, who lives in Canada, bring one for Christmas.
As you can see on the link, they ARE available.
Past discussions on line, if I remember correctly, identified two or three individual U.S. citizens who were so outraged by the censorship of a Disney children's movie, that they offered free copies to whomever asked for one.
Are the video and audio on the DVD you obtained of reasonably high quality?
The bootleg versions I have run across are of uniformly bad quality.
