1606? The map looks very much close to the actual world............
Especially the one on the right:)
When I was sailing all charts looked like works of art to me. The coasting charts had detail of prominent buildings, vegetation or mountains along coastlines etc, all on quality paper. The paper started going down hill about the time the gaffiti like loran lines sprawled over the charts. The loran lines are gone but the quality and detail was still down.
