All ages admitted. There is no content that would be objectionable to most parents. This is one of only two ratings dating back to 1968 that still exists today.
randomly found this on youtube with 2.6k views, and it is now probably my favorite version of the ugly duckling i am absoutlely in love with this short. there is something very comforting about it, i think i rewatched it at least 5 times today.
