Wikipedia's page on the artist, François Zdenek Eberl, says,

François Zdenek Eberl (1887-1962) was a Czech-born painter who worked mainly in Paris, France. At his prime, his name was included among those of fellow painters and personal friends Pablo Picasso, Amedeo Modigliani and Maurice de Vlaminck. [...] Drawing inspiration from the folklore of Paris, his preference was to paint the street scenes and nightclubs as he observed them.

How does that fit into Chess and Art Movements (December 2017)?
