Sloane Street, from 137 bus, 19th March 2009

This industrial brutalism is probably not how most people imagine one of the world's more exclusive shopping streets, but pipes need replacing and the world still turns. Above the incised street and below the bare concrete the designer shops still ply their pricy trade, but they don't as a rule rely on balloons to attract it, so where this one came from is, as so often, a mystery.
