The biggest and most influential name in the history of Dutch sea-charts was the firm of Van Keulen, founded by Johannes van Keulen, whose earliest collection of charts is reckoned to date from 1680. The business later increased in the hands of his sons and other descendants after his death.
The chart is undated, but was probably made sometime soon after 1750. Iceland is of the type that was common on many Dutch nautical charts at the time. The Western Fiords have turned in to two peninsulas, one pointing west and the other north, and the coastline is rather rough.
