Another Lowry Sale

This gloomy painting, An Old Church by L.S. Lowry, hasn't been seen in public since the 1940's. No great loss, you might think; but BBC News gets excited about anything by Lowry. It reports that this picture is coming up for sale at Christie's auction of 20th Century British art in London next month, estimated value from £700,000 to £1m. And it isn't the only Lowry up for grabs. There are three other major canvasses and a number of smaller works. Any other artists in the sale, BBC?
