This is a poster from the short Disney short Animation called  "The Small One" Which was made in 1978 and originally released theatrically by Buena Vista Distribution on December 16, 1978. Its a boy who lives with his father and four donkeys outside of Nazareth, one of the donkeys Is called small one and is the boys best friend, but out one day when working to carry logs his father works out that one of the donkeys is too old and cannot work any more. He then tells his son he must leave to sell the donkey but as its his best friend and he has to do it the boy has to leave to sell his friend and get silver from him, he has lots of difficulty finding someone and everyone rude to him at start but he finally finds a "friendly face" to take him. I feel like they based the donkey on Eeyore from "Winnie-the-pooh" sort of because he looks similar to him in my eyes/ears when u see small one in certain positions in the animation, the boy also reminds me of Mowgli from Jungle Book, by the style of the hair and the shape of the eyes. I love the style and the story's really sweet, the use of sound is very good the choice in the music and songs made up are really interesting to listen to, especially the song where the three traders are singing about their work/money!
