Found this interesting post on Grafik Warfare regarding a certain person who is selling genuine "street-signs" and doctoring them to make them look like they are priceless works of art. According to Grafik Warfare;"
"This sign for instance I know from the bottom of my road in Brighton, so it’s not from London. also that D*Face stencil was never on there. The whole thing is bullshit."
If this is true, then the person who just bought this for £4,000 GBP has been seriously duped and I feel sorry for them. It's unbelievable how far people will go to make a quick buck in this age of streetart/graffiti mania. To make fake stencils of others work is appalling.
