On Thursday I got four postcards: one from the Netherlands and three from Germany.
The card from the Netherlands shows Griend. Griend is a small island in the Dutch part of the Wadden Sea. It is one of the West Frisian Islands. It is uninhabited, but there are many bird colonies on the island. Since 2009 is the Wadden Sea on the UNESCO World Heritage List.
With a matching stamp:
