An article, oddly enough on Daily Kos, that is relevant to Earth-2:
America Before Pearl Harbor - Early Kodachrome Images. I'd forgotten that Kodachrome was quite that old. Lots of pictures on a number of subjects.
Of course, Japanese Americans on Earth-2 are not under suspicion, as their counterparts on Earth-1 were in this period. Chinese Americans
are, but they aren't being locked up, due to the influence of Earth-1 polities, including China-1.
