Stunning relief - tell us more! I'd like to be able to visit this piece.
I don't know who the artist is, but it is a familiar style and would love to know who created it. Incidentally, I've just noticed that Alfie's Spaces at http://www.bigartmob.com/view/337/ has it on Appold Street, EC1 (confusingly, the two roads continue into each other) - and a better framed pic too (maybe he's taller than me!) My notes say 8 Curtain Road, but I could be wrong. Maybe someone can confirm?
