Cute rectangle shaped metal pin badge, dating from the 1960s, titled Nederland Behoort Ons (= The Netherlands Belongs to Us), showing three features of the country:
a typical Dutch windmill
the shape of the country, from before the province of Flevoland was formed;
a lady in traditional costume.
 
The pin measures approx 27 x 16mms. It has obviously been used, but has been preserved well.
 
Just one copy. A very unusual find.
