I need something that can help me tell if a house guest has communist brainworms, but doesn't signal anything to the uninfected. I was thinking something like a print of one of the Diego Rivera murals where Lenin is lurking in the background. I need some more ideas. It could be music, some choice phrases, some prominently displayed literature, etc. But it has to only be meaningful or interesting to the already initiated.
Edit: My wife is pretty sure that a normal American does not know what Lenin looks like. However, a portrait of Lenin won't work as a shiboleth if I'm asked to explain who he is.

Oh... that's my great grandpa from the old country!
He's interesting. He lived in Germany for a bit and then moved to Russia. That was a really long time ago.
With the picture of Stalin I'll tell them it's my wife's boyfriend's dad.
Is talking about your wife's boyfriend a good way to id people that spend too much time on this website?
nah, is discussed on 4chan and other websites, appears sometimes on reddit and instagram.
Yeah, uhh, that picture came with the frame.
