Belgium: Ostend

Today I got four postcards: three from Belgium and one from Germany.

One of the cards from Belgium shows various views of Ostend.

Stamp:

Gebrielle Petit was born in Tournai in 1893. After the outbreak of World War I she started to serve with the Belgian Red Cross, but later she also spied for the British Secret Service and helped several young men across the Dutch border. She was executed by the Germans in 1916 and became a Belgian national heroine after the end of the war.

Thank You very much William!
