I use the OPTIC method of visual analysis to interpret each of these Dr. Seuss and Disney images regarding WWII. I then follow with the short "Education of Death" or "Der Furher's Face" starring Donald Duck.
I have used this when discussing propaganda, total war, American involvement in WWII, domestic issues regarding WWII, Nazis, fascism. This can be done as whole class instruction, or using the OPTIC method in small groups, with discussion questions to follow.
One year, this served as the documents for a Document Based Question (DBQ) accompanying the question, "Analyze the ways in which American cartoonists encouraged American support of World War II."
