Echecs - Championnat de France (1925)

Here we have a nice poster for the French national chess championship played in 1925.
The event took place in the beautiful city of Ni ce between September 2 and 11.
The picture is somehow monochromatic but it goes with the cubist aesthetics so in vogue at the time.
As in a painting by George Braque or Juan Gris, a group of cubes (tridimensional squares?) flow over the background, the silhouette of a King.
I did some research in Wikipedia and it seems the champion that year was Robert Crépaux, who had also won the title the previous year in Strasbourg and would make it again in Paris in 1941. One of those inconnus we are indebted with.
