LAGO VISITORS BOOKLET - IN DUTCH
This is a booklet, which was written in Dutch and given out by Lago to those who took their refinery tour.  This was an outreach project undertaken sometime in the late 1950's. for people living on the island.
Dolfi Kock and his family, and I understand it was a family undertaking, provided an English translation of the booklet.  Thanks to all the Kock family.
