Map people, I need your help! What projection might have been used to create this map? Note how the meridian have a distinct bend in them at around 80 degrees north.

This is as close I get to recreating the map. Azimuthal Equidistant projection centered on 55°N, 5°W.

For the perfect map of the Danish Realm I think the projection center needs fine tuning, but this is a good starting point.

Here's a new version with tweaked projection parameters and an attempt at mitigating the vast difference in size between smallest and largest country. Is it clear to you what's going on?
