I rode the Southern Crescent in both 1977 and 1978, but I probably collected these in 1978 with yesterday’s timetable. The first is a nice piece of stationery that shows the Southern’s distinctly painted E units and the logo with the C in a crescent-moon shape.

Second is a napkin that doesn’t specifically mention the Crescent, but since it was the railway’s only passenger train at the time, it wouldn’t have been used anywhere else.
