Great picture Nellie.
I was interested to see the comments about the national symbols, and the oak leaf comment puzzled me, as being Britsh I always thought of it more as a symbol of England than the whole of GB. So I looked it up on wikipedia (not always completely accurate). Here are some interesting excerpts from it .........

"The oak is a common symbol of strength and endurance and has been chosen as the national tree of many countries. Already an ancient Germanic symbol (in the form of the Donar Oak, for instance), certainly since the early nineteenth century, it stands for the nation of Germany ..........
Other countries have also designated the oak as their national tree including England, Estonia, France, Germany, Moldova, Romania, Latvia, Lithuania, Poland, the United States, Wales, Galicia, Bulgaria, and Serbia.[29]

The oak is the emblem of County Londonderry in Northern Ireland, as a vast amount of the county was covered in forests of the tree until relatively recently. The name of the county comes from the city of Derry, which originally in Irish was known as Doire meaning oak.

The Irish County Kildare derives its name from the town of Kildare which originally in Irish was Cill Dara meaning the Church of the Oak or Oak Church.

The oak is a national symbol from the Basque Country, specially in the province of Biscay.

The coat-of-arms of Vest-Agder, Norway, features an oak tree.

The oak tree is used as a symbol by a number of political parties. It is the symbol of the Conservative Party in the United Kingdom. In the cultural arena, the oakleaf is the symbol of the National Trust (UK) and The Royal Oak Foundation."
