I love seeing how things actually get made. This set of Flickr photos shows the shop that manufactures the highway signs for Washington State.
As successive photos reveal more of the underlying letters, and the visible part seems to be “ypo,” I find myself fantasizing that it will turn out to be spelling “Typography” – or perhaps the little-known Washington town of Typopolis. It is, however, “Keyport.” Oh well.
