From what it sounds like, "concealed propaganda", would be propaganda that is subtle, trying to slowly edge under the skin of a reader, in order to make it seem like it fits in normal life. They sound familiar to news you would hear otherwise. "Revealed propaganda", would seem like it's very blatant propaganda, like what you see in politics, with almost every ad or poster smearing one thing, person, opinion, etc. Revealed propaganda tries desperately to make people join it's cause and hate the other thing. Hope this helped!
