Grand Prix de la Marne
The Grand Prix de la Marne was a Grand Prix motor racing event, organized by the Automobile Club de Champagne and staged at the Reims-Gueux public road circuit, 7.5 km west of the city of Reims in the Marne département of north-east France. It proved to be one of the fastest and most prestigious road races in Europe.

History
The origins of motor racing in the Marne district of the Champagne region date to 1912/1913 motorcycle competitions held on a 225 km road course referred to as the Circuit de la Champagne à Reims near the town of Sarcy (about 20 km west-south-west of Reims).

The first event for automobiles was held on August 2, 1925 at the 20 km Circuit de Beine-Nauroy (approximately 10 km south-east of Reims near the Reims-Prunay airport on road D-931). In 1926, the Grand Prix moved to the Reims-Gueux circuit, starting an annual series to run un-interrupted until 1931. By 1932, the popularity and success of the race prompted the French Automobile Club to host the French Grand Prix (billed as the XVIII Grand Prix de l'ACF) at the then 7.826 km circuit, to return in 1938 / 1939 under grand prix regulations, two non-championship rounds in 1948 and 1949 and under Formula 1 for another eleven editions at various years from 1951 to 1966.

Except for the 1926 Coupe d'Or (the first 12 hrs of Reims), the 1932 Grand Prix de France at Reims was first major race not billed as the Grand Prix de la Marne even though a few contemporary sources and regional interest continued to refer to the ACF sanctioned Grand Prix de France as "Grand Prix de la Marne". Various race name and numbering systems are still in use today.

A typical example among the editions published under different race names and/or numbers is the 1952 Grand Prix:
