Banksy Graffiti

The famous "Falling woman with shopping trolley, pearls, purse, and wine bottle. Plus shadows." What can it all mean?

A very recent Banksy from November 2011, on Bruton Lane in Mayfair. Apparently it's called "Shop Til You Drop".

Probably the only reason this has not been vandalised yet is because it's so high up. You can see lots of street level graffiti has been added more recently. Including some from rival graffiti artist Team Robbo who added his tag plus the comments "No escaping us Sonny xxx" and "you will need a cherry picker to put perspex over this one council".
