Often, in movie theaters, the lead in features were related to news events. Newsreels kept people informed as to what was going on in war (though sadly dated because of time constraints and distribution). These cartoons offered a broader brush. Here, a duck is born from a black egg and rises with a swastika arm band and a famous mustache. Soon the barnyard is being recruited by this figure plus one that looks like Mussolini and another being Hirohito. So what transpires is that peace efforts fail and soon the peaceful must rise to the occasion. This is well done and I am sure bolstered some people's hopefulness.
