Who made the map? Rendsburg,not berg and Schleswig and Flensburg are not landlocked ,but connected to the Baltic by the Schlei and Flensburger haf. there has to be a more accurate map,not to mention the omission of the Friesland islands my Mother will be severely upset. Also from the Danish side Tondern/Tonning,not Tender.
Actually, it's 'Tønder' in Danish, but that map is wrong on too many levels, placing the towns/cities completely bonkers (for example, Faaborg should be where Svendborg is, Svendborg in reality being situated at the south coast of Funen, just north of Ærø and Langeland (and Taasinge and Thurø, which have been left out), and the harbour town on Zealand should be Korsør, not Slagelse, Fredericia is not on Funen but in Jutland, etc.
You can draw a much better map by printing a google map of the region and draw an 'overlay' (those with a good drawing application might even be able to do it digitally).
