This is an interesting example of re-using old stock. James Wyld published in 1845 a ‘Post map of Europe’, showing routes of communication throughout Central Europe.

The map was printed by using a technique called copper-plate engraving. The image would be incised onto the plate which is then inked, the top surface is cleaned leaving the ink in the cuts, paper is then pressed down onto the plate. This plate could then be stored and re-used as needed, either in producing further editions of a popular map or, in this case, by changing some of the details and producing a new map at minimal cost. Being a soft metal meant that it was easy to alter or even remove information.

Front and back covers for the new map, the only real change, along with the removing of the year published, in the map.

Wyld’s Post map, with the removal of the year originally published and given a new cover (but not a new title on the map), becomes ‘Wyld’s map of the theatre of war’, the war being between Prussia and Austria in 1866. The outcome, a relatively easy victory for the Prussian Army in seven weeks led to the creation of the North German Confederation. Following war with France in 1870 the remaining German states joined this Confederation, creating a Germany that was to last until the end of the First World War. Wyld’s map illustrates well the confusing make-up of the different states before unification.

James Wyld was the middle of three cartographers, father, son and grandson, all called James. The father was Geographer to George IV and William IV while the James who produced this map was Geographer to Queen Victoria. As well as produced a large number of maps he also created

and exhibited a ‘Monster Globe’ for the Great Exhibition in 1851. This was a giant model of the Earth which was viewed from the inside.
