[WWI] German invasion of Belgium - Postcard, 1915

Belgium to Paris, France; the stamp has been postmarked 'Ste. Adresse Poste Belge Belgische Post 28 X 15'.

During World War I, Sainte-Adresse was the administrative capital of Belgium. The Belgian government in exile was installed from October 1914 to November 1918 in the Dufayel building, named after the businessman who had built it in 1911.

The area had at its disposal a post office using Belgian postage stamps, and a special postal registration label, LE HAVRE (SPECIAL). A postmark was also created for Ste ADRESSE/POSTE BELGE - BELGISCHE POST.
