How would you go about hiding...unsavory wall art from guests?

I thought this might be a fun question as my husband and I try to figure this out ourselves. LOL!

So, we're in the process of decorating our place and we want to hang some erotic art prints eeeeeverywhere, because we're freaks like that. Don't you dare judge us. 🤣🤣

The only issue is that we live in an apartment, so there are times when we'd have others come over. Neighbors, maintenance, pest control, etc. Instead of going through the michigas of taking the prints down and rehanging them every time someone came over, we were trying to think of a simple way to conceal them whenever someone came 'round.

My husband suggested some kind of double-sided poster frame that we could flip, which in theory seems easier than taking down/rehanging, but still feels like a lot of work. I, on the other hand, suggested using wall curtains, which runs the risk of drawing interest like, "Ooooh, what's under there?!" HAHA!

Apart from the obvious "Don't hang it at all", how would you handle this?
