Sint Maarten (Netherlands Antilles), 1987

Saint Martin (in Dutch Sint Maarten) is an island located about 240 km away from Puerto Rico, in the northeastern section of the Caribbean. It is part of the group of Windward Islands in the Lesser Antilles and is the smallest inhabited island to be divided between two different states: the southern part, known as Sint Maarten, constitutive nation of the Kingdom of the Netherlands, until 10 October 2010 was part of the Netherlands Antilles, while the northern part is an autonomous overseas collectivity of the French Republic. In 1987, telephones with optoelectronic technology were installed by Landis & Gyr in the part of the island that then belonged to the Netherlands Antilles and two gray cards similar to those used in the other islands were issued: a value of 60 units with code 709A and one of 240 units with code 709F. 2,000 were printed for each value. Other similar cards, but lacking the characteristic red arrow, were issued in 1988 and 1989; then, in 1991, optical card phones were replaced with other ones based on chip technology.
