These are the cartoons produced by the Dr Seuss dude during World War II (1942-44). It's not exactly Green Eggs & Ham; shows how war can bring out the ugly side of a people. Very interesting though and probably excellent for some class activities or resource design. The images of Japanese are decidely un-PC.
An excellent collection of sources on all things World War II. Focusses on: life at the fronts; the holocaust; Japanese war crimes ("War crimes, what war crimes?"); photos & posters; and the nuclear bombing. With primary sources and well-organised.
