Antique maps are great fun to collect. If you wish you have a theme to your collecting such as buying maps of your home county or if you have moved about a bit then the counties you have lived in over the years. Or you can just buy the maps that you find exciting just because of perhaps their decoration or their historical interest. It could be a collection of maps by a single cartographer or maps from a particular century. Lots to think about
If your Interest is British County maps then you will probably find my ongoing project to offer more information on the amazing cartographers whose works you might want to collect. Still in its infancy and a lot of work to do but please check it out.
