"Divider" is Clovis Didier

Nellis Auction, from Las Vegeas, USA, sells on 28 August 2016 in a house sale an "oil painting signed Divider dated 1899", no estimate, current bid $30. (no good picture or dimensions)

It is actually a work by Clovis-François-Auguste Didier (born 1858), a French painter of landscapes and genre scenes (usually with woman). His paintings fetch wildly varying prices, from a £500 landscape at Christie's in 2009 to a $30,000 scene at Sotheby's.

Dorotheum valued this lot at $8,000.

This lot was valued $6,000 by Sotheby's in 2008.

It is hard to tell from the picture, but this work seems to be less refined than his best works. It is perhaps closer to the above work, sold at Tajan in Paris in 2015 and estimated at 800 Euro. A price of about 1,000 Euro seems right for this one, so far it is a bargain. But without better pictures, it remains a gamble of course.
