It’s hard to believe, but Dr. Seuss wasn’t always a liberal extremist when he tackled political topics. Check out this cartoon from October 1941:
There’s a whole series of these anti-appeasement cartoons by Theodor Seuss Geisel in the Mandeville Special Collections Library at the University of California at San Diego. All of them are from 1941, and all are from before Pearl Harbor.
It reminds his fans (of which I am one) that Dr. Seuss had a long and varied career.
