Although not published until 7th August the following quote comes from chapter two of William Gibson’s Spook Country.
“The old man reminded Tito of those ghost-signs, fading high on the windowless sides of blackened buildings, spelling out the names of products made meaningless by time.”
William Gibson, from Chapter 2. Ants In The Water, Spook Country
I like this description of ghost signs and the way that their companies and brands have faded in meaning in much the same way as the advertisements have done. From what I know of William Gibson he writes mainly sci-fi stuff so I might not read this book but will probably skip to chapter two if I see it in a bookshop.
