This was once the heady height of modernity. Air travel was still expensive, and the trains still ran on coal, but Britain had a shiny new motorway system, and for the cost of a gleaming car, it was yours to explore. Oil was cheap, and as far as anyone could tell, would remain cheap forever.
Adding even more texture to it, a number of the ads are in Russian. The book was produced for an exposition in Moscow; perhaps, at the height of the brief thaw of the Khrushchev administration, the executives of Rootes imagined that Russians may soon be enjoying a version of the British take on the American Dream?
I had a ride in a friend's Sunbeam Alpine earlier this year. I must say, it wasn't quite as good as it looked (though, hey, it looks ace!)
