Information:
Louis-Eugène Mouchon (Paris, August 30, 1843-March 3, 1914) was a French engraver, especially noted for its stamp designs. His most famous pieces are the famous French type MOUCHON designs from 1900 and its contribution to the subsequent La Semeuse (from 1902), but he was also asked in many European countries for his designs. He made portraits of the Belgian King Leopold II, the Portuguese kings Louis I, Carlos I and Queen Wilhelmina. (Source: Wikipedia, Read more about Louis-Eugène Mouchon on Wikipedia (Dutch))

Information:
King Albert I (8 April 1875 – 17 February 1934) reigned as King of the Belgians from 1909 until 1934. At the beginning of World War I, Albert complied with a British demand that he not acquiesce to a German request to move troops through Belgium in order to attack Britain's ally, France, which Germany anticipated was about to declare war on Germany in support of Russia. Albert responded to the German demand to move soldiers through his country: 'I rule a nation, not a road!' When Germany subsequently invaded Belgium, King Albert, as prescribed by the Belgian constitution, took personal command of the Belgian army, and held the Germans off long enough for Britain and France to prepare for the Battle of the Marne (6–9 September 1914).
