When I was alad in the late 1940s, I used to be interested in the poster type arrival and departure notices that were strategically placed around the station. I recall that the arrivals were blue on a white background, and the departures black on a yellow background. (It could have been vice versa!) Has anyone got any of these to sell or allow me to copy? They were about two feet across and three feet long. Now that I am 76 years old, I would love to see them again. Alan.
