After the party to end all parties last night, I spent this morning in central-ish London retrieving detritis from the Tate and transporting it back to Chiswick. On my way between the two, our car stopped under the bridge just down the road from the Tate Modern – where this sight greeted me. It’s a really cool thing to find under an otherwise dingy bridge – as far as I can tell, it’s not an advert or anything, just a bit of… art?
