Ours

I saw this sprayed on the 800+ year old wall by the south gate of Newcastle castle as I was passing through on my way to Gateshead this morning.

"Mine", wrote the wee nyaff. You're wrong, baby, you're wrong (to quote the late great Michael Marra). It's OURS.

Edit: I find that I blipped the south gate itself almost exactly two years ago - the archway on which MINE is now written in capitals (just to the left of this shot). Although at least Lee and Podger seem to have refrained from writing on the archway.
