Yeah, I honestly think it's really interesting! More specifically, Seuss was in the Signal Corps to make propaganda like this alongside other artists you might know such as Stan Lee! Lee even made propaganda/survival comics for troops since a lot of them couldn't be bothered to read manuals for a lot of their equipment lol.
Holy shit, that's awful lmao. The only real thing from that entire pamphlet is that there's no real difference between L and R in Japanese (Think of ramen for example. It was a borrowed/translated word from Chinese: lo mein.) But I guess that's why it's propaganda in the first place.
Well that's why it's weird, because I seem to recall he was sympathetic to the nazis, while this picture is mocking the concept of america first by pairing it with an unsightly person representing the nazis.
