This cartoon may be the only of its kind and era to fully feature the subject of slavery. Other cartoons of this vintage include many degrading racial stereotypes, but this animation delves unashamedly into the subject - thus capturing (in the unassuming way that the passing of time has on perspective) the social norms of time and place, however unpopular we now so self-righteously claim them to be. This cartoon strangely enough is more light-hearted in its direct approach to the subject, but the fact is that more harmful subtle indoctrination of impressionable minds has happened throughout history (in cartoons, children's records, books - towards African Americans, Native Americans, and every other race) and continues to happen in modern media- in a more tasteless manner than ever.
BUT, these sorts of racist documents, experienced discerningly, can be incredibly valuable and interesting gems.
The animation itself is a zany orchestration of images to the music accompaniment, and the images may actually accompany the music more so than vice versa. Pioneering a skilled art form, the style of animation of this time was real funky and fun.
Highly recommended to anyone interested in the history of film, animation & social absurdity.
