Younghusband of Cominganarchy.com emailed me a link to this fantastic WW2 era comic book format guide to distinguishing evil conniving Japs from friendly smiling Chinese. It was originally just one chapter of a larger Pocket Guide to China, the remainder of which is sadly not preserved. As a bonus though, you can try and figure out how these odd spellings of Chinese words are actually supposed to make the sounds that they are supposed to make.
