An interesting coincidence: in 1967 (the year of Siegfried Sassoon's death), Time published another volume in its Time-Life Books/Life Science Library series. The subject was transporation: cars, roads, bridges, etc. And the principle author was a prominent expert in transportation issues in the 1960's. The title was Wheels, and the author, Wilfred Owen.
