Many years back I worked for the Disney Company & one of the benefits of working for the company back then was that you could borrow any of the Disney movies from the Disney Studio, for the weekend. The company would also loan you the projector (16 mm) & if the movie was a wide screen movie they would furnish you with a special lens attachment to view the theatrical release aspect ratio. Disney had a wonderful selection of top notch movies available to borrow. At that time the majority of movies were actually live action not animated although of course there were a lot of animated movies also. Walt used to have the Disney classics re-released every so many years so that the new generations could enjoy them. Sadly today the shops/stores seem only to carry the recent animated movies. You very rarely see those old classic movies that I am referring to. So when I saw some of those of my favorite movies available on line I had to buy some. "The Island at the Top of the World" is one of those & it is still as appealing as it was 30 plus years ago.
The Disney Company kept the movie master copies in Black & White as Black & White masters last for a hundred years whereas color masters deteriorate much more quickly. The company could make a crisp fresh copy in color using the B&W master. Consequently each re-release was as good as the original. The recent DVD copies I have purchased on line lack some of the quality of those earlier re-releases. However they are still adequate to watch & enjoy. And if you haven't seen these older Disney movies you are missing out on a great selection of very well done wholesome movies. "The Nine Lives of Elfego Baca", "Dr Syn Alias the Scarecrow", "The Ten who Dared", are just a few of those great movies that appear to have been lost to the new generations.
