A very nice original WWI French Croix De Guerre 1914-1916 here, complete with a single star device on it's original ribbon. This award is the 2nd variation of the WWI cross, with dates ranging from 1914-1916 on the reverse. A separate version exists for each year that the war continued. 
 
The Croix de Guerre is a military decoration of France. It was first created in 1915 and consists of a square-cross medal on two crossed swords, hanging from a ribbon with various degree pins. The decoration was first awarded during World War I, again in World War II, and in other conflicts; the croix de guerre des théâtres d'opérations extérieures ("cross of war for external theatres of operations") was established in 1921 for these. The Croix de Guerre was also commonly bestowed on foreign military forces allied to France.
