A possible Aert Van der Neer

Spanish auction house Alcala sells, in a generally interesting auction, a "Dutch School, 18th century" landscape, estimated at 1,500 Euro. UPDATE: sold for 1,500 Euro.

It looks a lot like the works of Aert van der Neer, celebrated 17th century Dutch painter who specialized in these moonlit riverscapes. Of course, he had many followers and derivative artists, but the quality of the one for sale here is fairly good.
