I saw this book at Barnes and Noble the other day and had to pick it up.

Dr Seuss Goes to War

I had never heard of his WWII political cartoons and have enjoyed them quite a bit. Here are a few:

About Isolationism:

Racism at home:

Hitler:

And Laval:

There is commentary that accompanies the cartoons. It looks pretty good although I haven't read much of the text. I'll add more later.

I'll post larger images here: http://picasaweb.google.com/OBrienPhotos/Military#

I seem to remember hearing a little about it, but I've never seen any of them.

Great find!
