British Railways Southern Region poster for the Southern Belles (Bournemouth and Brighton Belles, that is). Use of the totem logo dates this as pre-1965 and from the style I would put it as early 1960s. It features a well-dressed waiter holding a Pullman coach against a striking pink background.
The main text reads 'You can dine and wine on these all-Pullman trains every day of the year'. The reader is also invited thus: 'For further information please enquire at stations and travel agents'.
I suppose the demise of services like this (the Bournemouth Belle ended in 1967, the Brighton Belle in 1972) is progress of some sort.
