A man holds a placard during a protest next to a section of a wall where celebrated street artist Banksy's 'Slave Labour' graffiti artwork was removed in north London on February 23, 2013. The work that showed a young boy using a sewing machine to make the British flag has been carefully removed and will be auctioned in Miami where it's expected to fetch around 328,000 GBP (500,000 USD). Residents of the North London area have reacted angrily to the removal of the work, but the auction house says the piece was acquired legally. AFP PHOTO / JUSTIN TALLIS
