That dvd is from a line called Disney Treasures. It started in 2000 under the wing of Roy E. Disney and Leonard Maltin was the series host. They would release limited number editions of 2 to 4 different types of Disney programs on double disc sets every year in December. They released all the Mickey Mouse, Donald Duck, Goofy cartoons as well as all the Silly Symphonies. There was each a set for the first week of the Mickey Mouse club, the Annette, the Hardy Boys and Spin and Martin serials. The last set released in 2010 was the complete Zorro programs (they also had Davy Crockett, Scarecrow of Romney Marsh and half of Elefago Baco). I have not checked lately, but for a time if you were a D23 member you could order all the sets released over the 10 year period. Expensive, over $500. Five of the titles featured complete shows selected from the Wonderful World of Disney programs. The ones I have are the Tomorrowland, Behind the Scenes of Walt Disney Studios, Your Host Walt Disney and
Disneyland USA in addition of the one you mentioned. I would love to see them release some more of that programming.
