You know these symbols which you see all over town? You know how they can be quite different?
There's a book for that.
Phil Carter published this little book of bike lanes, in all their manifestations, as the result of recording his daily commute to and from the studio. It's called Code 1057 after the name of the Road Marking Diagram the symbol is derived from.
I think it's out of stock now, so keep an eye out on Abe Books for it. I've just ordered a copy.
