All around the east end there are pieces by Sweet Toof, they are not exactly difficult to spot, seeing as they are usually huge and pretty bright.
On my daily mooching around London today I cycled a different route and saw this parked up under one of the arches near the Hoxton Tube station. It would seem that Street Art is now on the move as well, maybe it is for a Sweet Toof roadshow, or maybe not.
Sweet Toof also leaves pieces around the place for eagle eyed Londoners to keep, a mate of mine found a copy of the Metro with the cover completely transformed with the trademark Sweet Toof design. Lucky get!
