William S. Thomson was a Scottish photographer who roamed his beloved country during the 1950s. Based in Corpach, Fort William, he produced about 20 smaller booklets, focused on different regions, in the Let's See Scotland series. His books The Highland in Colour, published by Oliver & Boyd in 1954, and Colourful Scotland, from the same publisher in 1956, can be seen as overviews. For Travel in Time I rediscover the Highlands and wonder in Thomson's footsteps.

The Highlands in Colour (1954, Oliver & Boyd) was W.S. Thomson’s first book with pictures of Scotland. Thomson travelled on the Scottish roads not only for his own project but also for the voluntary Scottish Tourist Board (STB) which was set up in 1946 and consisted of representatives of the main organisations in Scotland with an interest in tourism, together with four people appointed by the Secretary of State. This STB had no statutory powers and was based in a former church in Rutland Place, Edinburgh.

The Scottish mountaineer and writer William Hutchison Murray Seton Gordon (1913–1996) wrote the introduction.
