This Alfa Romeo Mille Miglia poster celebrates the 1930 event.
The 1930 race was the fourth Mille Miglia event. This endurance contest was won by the great Tazio Nuvolari driving an Alfa Romeo 1750.
The race was run every year over a figure of eight course covering a thousand miles, hence the name, and starting from Brescia the route runs via Rome and back again to finish finally in Brescia. In the 1930 event, Nuvolari cheekily surprised his great rival Achille Varzi by overtaking at night with his headlamps switched off, and this is the moment that the poster illustrates.
