Last week, on May Day, I found this cryptic symbol sprayed on the pavement next to a bus shelter on Hill Lane in Southampton:
I photographed it mainly because of the shadows, of course. Then, at the weekend, without realising what I was looking at, I found something very similar in a tunnel under the railway line near Hockley Viaduct outside Winchester:
Is it an "R"? Or a "12"? Or is it the common symbol for some infrastructural object -- pipes or wires, maybe? It seems too simple, discreet and utilitarian to be someone's grafitti "tag". I'm intrigued.
