Upon doing some research for my lessons for next year, I was pleased to come across this resource--on Pinterest of all places. I do a lot with propaganda in my class when looking at visual rhetoric. I typically focus on WWII propaganda, but I really like the idea of timing this unit with the US History teacher and focusing on communism, maybe while he's teaching about the Cold War. This collection of propaganda posters (which appear to me to be mostly Chinese and Japanese) will also allow you to access their various urls around the web, as well.
