We have spotted a number of these pieces on the streets of East London and suspected that they may have been created by the Toasters. That has now been confirmed by the Toasters who dropped us some pictues of the work via email. Here is what they had to say about their latest project "Bluff Buff"

'Bluff Buff' is our reaction to the authorities obsession with painting inaccurate coloured shapes over graffiti. We paint the Toaster silouette beside these buff marks. It is an inconspicous and subtle attempt of getting up and highlights the ridiculousness of the pre exsisting council cover ups.
The Toaster form resembles the adjacent buff so conceivably there is less chance of the it being buffed. No tags are harmed during this project.
