The hole in vinyl LP paper sleeves.
They're the polos of the music world.
What I do is: I remove the record, in its sleeve, before placing the cover on top of my right speaker. Then I take out the record, and play it. Then, I take the empty sleeve, and put it on top of the front artwork, arranging the hole as best I can, to get the coolest small circular picture.
Just me?
