At the Gemeentemuseum in The Hague, beside Liebermann and an Art Nouveau exhibition, there is work on show at the moment by the Belgian painter Jean Brusselmans (1884-1953).
I wasn't familiar with his work, and find it variable in quality, but I rather like his interiors with human figures and his portraits.
I particularly like the blue attic room with the seemingly depressed woman, of which there are other versions too.
In all the other works here above we see mrs Brusselmans.
It looks like her black-and-white dress was a particular favorite of Brusselmans, or indeed of hers.
