My fiancé is letting me help decorate our future home, but she says it cant be too nerdy. Does anyone know of any super subtle Harry Potter decor that someone might not notice at first glace unless they are a fan?

Hey guys, I’m in the process of building my new home and I don’t have one ounce of creativity in my blood. I’m trying to think of ways to very subtly incorporate a few Harry Potter pieces in my home. I really want some subtle/minimal (?) artwork for hallways (like a landscape of the castle or maybe of a snowy owl, or some stags) and some accessories. I was thinking of things that would blend in easily to some more adult styled modern decor, like a time turner clock or the dragon egg from the first task. I was wondering if you guys could help me come up with ideas or if you have links to pieces or shops that I can find what I’m looking for. Thank you :)
