The cartoons included on the set are uncut, unedited, and digitally restored and remastered from the original successive Technicolor film negatives (or, in the case of the black and white shorts, the original black and white negatives). However, some of the cartoons in these collections are derived from the "blue ribbon" reissues (altered from their original versions with their revised front-and-end credit sequences), as the original titles for these cartoons are presumably lost.
