First World war cartoons

Mar 2016
Hi I am making cartoons teaching children about world war one. What topics are of top priority? How should I present the great war?
I have already had teachers out of nowhere leaving comments saying that they are using the videos in their classrooms which is awesome.

The Assassination of Archduke Franz Ferdinand Cartoon (1914)

The Battle of Verdun (1916)

Trench Life

The Red Baron
