Bon Voyage

This week's Saturday Timewatch features a classic rail poster displayed at Swanage Railway's Corfe Castle Station. Superb detail can be seen on large size. For example, is that an argument going on at the bottom left corner?

 

Questions!

Do any of the railway bods know where this is??

Likewise, does anyone know the artist? The signature in the bottom left corner looks something like 'Cuneo'???

The artist is T Cuneo.

The location is Calais, France.
