This is a door decal that makes any 30" x 79" door look like a TARDIS police box. You can find them on Amazon from different sellers for $27 - $50, depending on how much you love or hate saving money. I'm not going to get one. Not because I don't like them, but because I already bought that TARDIS fridge decal, and the last thing I need is to be heading for a midnight snack and fall down the basement stairs.
Thanks again to carey, who promised to buy me one but didn't bother asking for my address or anything so she could actually send it to me so I'm not getting my hopes up.
