Dear all Does any one know where I can find out more about John Brion, a geographical modeller and constructor of relief maps. Is there a good bibliographical reference book to cartographers which might include him? I have an advert which gives a description of different types of services he offers. That is stuck on the back an 1858 1" raised relief map of the Environs of Brighton. However I am interested in finding out when he was born, died and what other things he worked on. I know that some of work was published by Edward Stanford. On a slightly related note, does any one know how easy it would be to remove nicotine stains from a hand coloured wooden relief map? The 1" map of Brighton was probably hanging in a pub for many years, which is how it aquired the nicotine stains. It would be interesting to have them removed, but not at the expense of the original cartographic work. Kind regards Timothy Langner
