August Macke's death anniversary cover

Today I got not only four postcards but also a cover from Germany.

Stamps:

August Macke (issued 01-09-2014)

Centenary of World War I (issued 07-08-2014)

with a special postmark about the 100th anniversary of August Macke's death

August Macke was born in 1887 in Meschede and was one of the most important German painters of the Expressionism. He was also a member of Der Blaue Reiter. When the World War I started August Macke volunteered and was conscripted on 8th August 1914. On 26th September he was killed at the Western Front. He is buried at the war cemetery in Souain. 

I sent this cover to myself to get the special postmark.
