Mickey Mouse and Donald Duck Cartoon Collections

[Big Disney Fan]

Does anyone remember these? They were the very first attempts at releasing individual cartoons on home video, two years before the Disney Channel even (meaning they were released in 1981)! Each video contained six shorts, two Mickey shorts, two Pluto shorts and two Donald shorts. Goofy never had any of his shorts in them; the only time he appeared was if he was in a "trio" short. Why did Goofy never have his shorts released on this set and did they have the "Walt Disney and You" ad at the end?
