There was one spokesman, an Englishman married to an inhabitant of the island, and he gave me some of the information. But he also spoke in the ship's auditorium to all the passengers. I also spoke to 3-4 vendors among them as I purchased their artifacts. They were exceedingly well priced.
They probably do board cruise ships visiting (13 were scheduled for 2014). They worked like well-practiced bees in a beehive, unloading boxes from the false floor on the boat, and setting up tables to sell their ware on the ship.
They earn only 2% of their money they need to sustain themselves. The balance of 98% comes from the UK.
In the photo, they are approaching the ship. When they were leaving, they were even more friendly, having sold much of their carvings and stamps. They were generally a motley crew.
