ALM Antillean Airlines Network, Date Unknown.

Via this Dutch Caribbean website comes this vintage route map of ALM Antillean Airlines. The image is undated but does not seem to be contemporary with the end of the little airline's life in 2001, so could be from anywhere between 1985-1995, although the airline had its origins in 1964. 

The "Dutch Anitllean Airlines" logo sits over the mid-Atlantic ocean, the same light blue as the nautical  labels and coordinate lines. The airline's routes spoke outward from the ABC islands, with three separate services to New York, one via St Maarten, and two to Miami via Kingston, Jamaica. Port-au-Prince, Santo Domingo, and San Juan are also served. 

These tiny Dutch constituencies hug the massive South American coast, and likewise ALM's routes seem to skirt around the territory, particularly the southeasterly service which terminates at the Dutch-speaking Paramaraibo, Suriname, via Port-of-Spain, Trinidad and Georgetown, Guyana. Other, shorter routes pierce the mainland, linking major Colombian and Venezuelan cities with the airline's home airports, Queen Beatrix International in Aruba and Hato International Airport at Willemstad, Curaçao.
