This client asked me to recreate a map of the Vimy Ridge battlefield for the 100th anniversary memorial. She had obtained permission to use a historical map, and appropriate credit was added to the finished project. The client also provided me with a hand-drawn sketch of additional information she wanted to include. I incorporated multiple sources, including contour lines, to create a map which was handed out at the memorial.
The image on the left is cropped from the original map created by G.W.L. Nicholson (Map 7 in Canadian Expeditionary Force 1914-1919). The map on the right is the one I created for the memorial.
