Today I got not only four postcards but also a cover from France.
Le Bleuet de France (issued 10-11-2014)
Belgian Exile Government in Saint-Adresse (from set of two) (issued 23-03-2015)
It is a joint issue with Belgium.
After German forces occupied Belgium a Belgian Exile Government was installed in Saint-Adresse in October 1914. It stayed there until November 1918. The leader of the government was Charles de Broqueville. The Belgian King Albert I stayed in the non-occupied part of Belgium and never visited Saint-Adresse.
Thank You very much William!
