The path to the exhibition was lined with pennants, I recognised the British Union Jack, the three lions for England (the Royal Arms of England) and the red dragon for Wales ( Y Ddraig Goch). The only one I hadn't seen before was the yellow flag with the red dragon which I guessed represented Scotland (I found it's the the Royal Standard of Scotland).
The exhibition oepened with this dramatic display called the Queens Beasts by Tom Hiscock.
I think this is the The White Horse of Hanover below. These pictures don't do justice to how sparkly the beasts were in the sun.
