Norderney is one of the seven populated East Frisian Islands off the North Sea coast of Germany. The island is 14 by 2.5 kilometres, having a total area of about 26.3 square kilometres and is therefore Germany's ninth-largest island. Norderney's population amounts to about 5,850 people. In 1948 Norderney offically granted city rights and this year they celebrated the 75 Anniversary of this pivotal moment. For this event a speical postcard, special personalized stamp and postmark was put into circulation as you can see below.
To note the small postmark on the left which is the offical postmark of the city administration. As on the special cancellation on the right side too you can see the coat of Arms of Norderney.
Many thanks to Sarah for this great card!
