Here is a picture of the last part of a big poster project by Richard Furness. He has gone through the poster collection of the National Railway Museum and mapped each poster against its physical location! And published this informationa as a series of beautifully illustrated books.
The eight volumes of the series provide a visual and topographical index of the collection. Brilliant.
I am very proud to have contributued to the project. The last volume includes my essay, How to Design a Railway Poster.
I posted the text of this essay a while ago, here
Congratulations and thankyou, Richard!
