Great VFYW today - reminded me of a website devoted to mapping Ghost Signs here in Chicago, produced by a grad student at the School of the Art Institute. It's an interactive map of the city; click on an area, and a map appears with red dots; click on a dot and you get a photo of the ghost sign at that location. A great piece of interactive scholarship, and a great way to while away idle lunchtime online minute. Or hours.
