In the early development of optical phonecards by Landis and Gyr, France was one of the early market goals for L&G. This is the earliest card manufactured for France. The deep blue was the color chosen for the French market, with variations of blue used until 1985. This “UN PRODUIT” design was also used on the prototypes for the Geneva university trials, but with a deep green color.
