We've noticed a very similar one with bomb and kids down Pages Walk. I'm quite certain it wasn't there before and has appeared in last few months. V cool and therefore I assumed it was a Banksy but not entirely sure. Next time I go down that way will take a photo and post it here.
I suspect if it was a Banksy someone would have knocked down the wall, removed the piece and sold it by now. Banksy's work is fetching crazy prices. I saw the graffiti in question on my way down to Tesco on Saturday; it's good.
That's a great picture. I'd be really interested to know who did the artwork. I have a couple of faux Banksy screen prints, which are sold from a small shop in Covent Garden. I wouldn't say no to a real Banksy in my living room, so long as it didn't feature any rats!
Has somebody noticed a new picture next to the children one near the tank? It seems that it appeared this morning. It definitely was not there by midnight yesterday. Strange, especially as it was raining at night.
