The bureau chief followed a link from Metafilter (cool in its own right) to Art Inconnu (Unknown Art), which is a beautiful site. Its purpose is stated thusly, "Collected here are works by artists who are forgotten, under appreciated, or little known to the mainstream". If you follow the link today, the works of an anonymous 15th Century Italian artist are displayed first but if you scroll down or click on any of the collections on the right of the screen, you will find that most of the works are from the 19th and 20th centuries. Also, almost everything in the collection is figurative.
A commenter on Metafilter pointed out that a lot of the "unknown" artists might be quite well known in their own countries and the bureau chief can testify that John French Sloan (1871 -1951) is in the collections of the biggest art museums in the US. Here's his "Six o'clock, Winter" from 1912.
On the other hand Zinaida Serebriakova (1884 - 1967) is new to the bureau chief but apparently well known in Russia and France. A self portrait from 1909.
Heinrich Maria Davringhausen (1894 - 1970) was driven out of Germany by the Nazis and his paintings were suppressed for being decadent. When he switched to an abstract style after WW II he changed his name to Henri Davring. The bureau chief knew none of this. This is his most famous painting, "Der Schieber" (The Black-Marketeer) from 1921.
The bureau chief had also never seen the work of the Scots artist Joan Eardley (1921 - 1963) who died way too young. One of her two subjects was the urchins that swarmed through the streets of the poor neighborhood were she had a studio. This is "Little Girl with a Comic".
Her other subject was the fishing village where she had a cottage. This is "Catterline in Winter".
Sometimes when you think the internet couldn't get anymore craptastic, you come across something really nice.
