Banksy offers up a tribute to graffiti writer Tox in his latest piece. Tox, in case you've never looked out of a train window, is one of London's most notorious taggers, and was recently convicted of criminal damage. Getting featured in a piece by Banksy will no doubt irk the authorities, raising his profile to new heights.
Update: We have a location - it's the corner of Jeffrey's Street and Kentish Town Road, NW1. (Thanks to commenter 'Buster's Dad'.)
Banksy also offers up this tribute to peace campaigner Brian Haw, who died a few days ago. The image can be found on the homepage of Banksy's website.
