Many thanks to Keith Gate of Contour Designs  for providing his A2-size Walkers Maps for display at the exhibition.  These beautifully crafted hand-drawn maps demonstrate the application of the various cartographic techniques mentioned above (simplification, map projection, typification and symbolisation, amongst others)  in conjunction with colour and elements of realism.  The scanned map extract on the left does not have the resolution or colour of the original.

Another excellent resource is the web record of a paper, on Heinrich Berann's landcape panaromas, by Tom Patterson of the U.S. National Park Service.  The paper discusses Berann's intuitive application of cartographic principles and techniques.
