Terschelling Flag!

I arranged a Facebook postcard swap with Lars van Rossum in the Netherlands in December 2014. The panoramic card which I received from him was of the Terschelling flag. 

Terschelling Flag

By decree, the flag of Terschelling was established as the flag for the municipality of Terschelling in the Netherlands on October 27, 1961. The colours are taken from the Terschelling coat of arms. 

A rhyme, in which the symbolism of the five colours of the flag is explained, was written in 1932 by Gerrit Knop. 

Read bin de wolken (red are the clouds),
Blaue is de lucht (blue are the skies)
Geel bin de helmen (yellow are the stalks), 
Griën is et ges (green is the grass)
Wyt is et sân (white is the sand) 
Dat bin de kleuren fan Schylgerlân (these are the colours of Terschelling).
