Subversion in Animation

I have decided to research into subversive animation in a world of propaganda and political correctness. Within this, I want to look at animation that internally defies governmental values, either targeting the dictatorships of the Nazis or the Soviet Union in the 20th century. So far 'The Hand' - Jiri Trnka, 'Breakfast On The Grass' - Print Pärn, 'The Silly Goose' - Hans Fischerkoesen, and 'The Glass Harmonica' - Andrei Khrzhanovsky are of potential interest. I will be noting down ways in which these films successfully get away with being subversive. I will do this by looking out for features that are similar in all of them. From this I can get a better understanding as to what makes an animation subversive, dependent on their environment.
