Tourist's map of Scotland
Tourist's map of Scotland, by John Bartholomew Junior, from around 1890. © Permission of Collins Bartholomew
This is a printed map of Scotland which has been hand-coloured.
What makes it unusual is that the colouring is a hybrid of two different techniques for showing relief — contour-layer colouring, where different colours indicate the height and depth of a landscape, and icons of hills. It's certainly not something we see very often.
This map features in the Bartholomew exhibition, which runs at the National Library of Scotland from 7 December 2012 to 7 May 2013.
