Bumper Stickers

[potioncat]

I happened to spot a "Star Fleet Academy" decal on the back of a car window the other day. I haven't seen on in a long time and it made me smile. Then it crossed my mind that I don't think I've ever seen a Hogwarts decal, or any other bumper stickers for Harry Potter. I've seen a vanity plate or two with Potterverse wording.

How about the rest of you, seen any interesting Potter stuff out there lately?
