Help evaluate the picture on the board, on the idea of someone from the Dutch
 

The picture on the board, looks very old, say that the work of the Dutch :)

Before asking a question about the assessment, you would think was worth, but whether, in principle, any substantive response only on such basic information? For those black spots - photos that you have given - generally do not convey any information.

Try again photographed, in daylight, not in the room.

A good idea to specify the types of wood, thick planks, the direction of fibers and the presence (absence) facets at the edges, board, whole or composite, monogram (signs) on the back (if any), the presence levkas on the back of the board.
If the paint is practically impervious to the photo and if the dimensions allow, try to scan.
At least in part, including inscriptions and signatures (if available).

well, I'll try that - do something, but the board from both sides is very dark, and I have no doubt that the whole, though I certainly will check it.

According to the image that is, can not even say with certainty that a Dutchman.

The owners say that she was about 400 and it can be Pieter de Hooch. Understand the type of wood and fiber is difficult, it is all in how the two sides covered with a dark composition, such as linseed oil or varnish (do not know how in those days was called composition), but it looks слабенько patent, the board does not really homogeneous, but from sostovnyh two, identical in size, seam tonyusenky, horizontal, is in the middle. In the evening try to add photos, the size of which is 40 - 45 (horizontal) by 20 - 25 (vertical)

But to whom is it like?

Such clothing from the Dutch 17 th century, I have not seen.
