Belgian brass plaque King Albert and Queen Elisabeth WW1

Belgian brass plaque King Albert and Queen Elisabeth WW1. This one was certainly made during ww1 since it says: Souvenir les Souverains Belges 1914-1915-1916. Later or post ww1 examples are usually dated 1914-1918 but since this one was made before the war was over it only goes to 1916, which is also the year it was made. A bit more rare then the ones you usually come across.
