“The King's Post” is a historical book on facts relating to the Posts, Mail Coaches, Coach Roads, and Railway Mail Services of the City of Bristol from 1580 to the time of its writing in 1905. The book offers an excellent view on how the need to communicate necessitated the setting up of courier services in Bristol and their subsequent evolution in sophistry, and the impact of postal services. As well as the various technologies that came up as a result. It is authored by Robert Charles Tombs who served as Controller of the London Postal Service, and later Surveyor-Postmaster of Bristol.
