Many of the links on this blog go to Amazon. If you click on any of these links and buy anything at all (it doesn't have to be a book!) I get a percentage.
This costs you nothing, but enables me to keep creating unique posts illustrated with images I've taken, usually especially for the blog.
You won't see stock photography here.
This photo doesn't have anything to do with this post, but I took it and I just fancied showing it to you. It's at Rocky Valley in Cornwall. There's no writing involved, but there are markings on a flat surface. It's communication.
