Some of the racist characters are definitely “of the time”. I always show them to my seventh grade civics students to point out how propaganda works (and to make sure they don’t hold their heroes too close).

Before he could find work as an author, Seuss had a run of amazing political cartoons leading up to and during World War II. They are archived at some college web site called “Seuss Goes To War”.

It looks like the educational website Kahoot. As a teacher, I hoped this was some open source version of it that I might more easily catch the cheating students in my classes.
