Incidentally, while I was on Canal Street today, I saw workman on a suspended scaffold who were in the process of scouring a ghost sign that read "SLIPKNOT" from the side of a building. I was standing there watching the piece being erased, and it served as a very immediate reminder of why I've taken an interest in these things. Basically, these signs are in the process of disappearing, and although the community is, at best, the barest attempt at a preservation effort, it seems important. I'd love to see your work there too.
That's all for now. For those who asked, your questions have been fed to the Info Tube. I'm sure answers will be forthcoming soon.
