Unrecognosed painting by Dunikowski, "best 20th century Polish sculptor"

Rops, from Belgium,  sells on 6 March 2016 a "Signed Danikowski 1921" painting titled La Sarabande, estimated at 200 to 300 Euro.

It is a work by Xawery Dunikowski, a major Polish sculptor who was also a trained painter but who has left very few paintings. He lived in Paris between 1914 and 1920-1921, so it may well be that this painting has stayed in Western Europe from the start.

It is very hard to value this work, as no comparable works have been on the market. His sculptures from the same period, which rarely come on the market either, have fetched around $40,000 when sold in Paris.

A painting from 1922 (a portrait; not really comparable, but same size and signature) sold for about $1,300 in 1992 at Agra auctions; but in many Eastern European countries has the interest in their own artists grown considerably over the last decades, so I guess that this may not be really representative. I would certainly be very surprised if this painting, properly atributed, would sell for less than 2,000 Euro.

UPDATE: sold for 2,000 Euro, exactly what I predicted for once ;-)
