What Harry Potter artifact would the above poster possess?

What Harry Potter artifact/object would the above poster have in his/her/their possession?

I've made a very lengthy list of artifacts below, or you can come up with your own that I've missed. Artifacts cannot be alive. Animated? Yes, just not alive. No pets.
Also I'm trying to stay away from things like wands, because that falls more towards particular characters, and really, cannot be possessed by anyone else.(unless you won it from them in a duel, that is. But let's be real muggles.) The Elder wand is one exception. And the broken wand. To clarify, you can have artifacts from particular characters. Just not wands. "The wand chooses the wizard," after all. Yeah muggles don't get wands see. Kinda sucks, sorry.
