While we're still on the subject of 'kinds of maps' that are available to the newbie antique map collector, here's another one for you. Thematic Maps will need to be added to your list of possibilities. The range of themes is just about unlimited and generally cover physical, political, economic and social aspects connected with a specific geographical area. If geography and especially mountain ranges are of interest to you then the map below is for you!

Many of these maps came into existence in the first part of the nineteenth century with the onset of the Industrial Revolution. The rapid technical advances in mapmaking and colour printing making this possible. The field of thematic maps is vast and interesting and its an area where you can build a collection for a relatively modest financial investment.
