Help identify the author
 

Good day!
Help, please, to determine the author of the picture or at least to the school of painting.
Painting: oil on canvas, 71 x 90 cm, frame 106 x 121 cm (presumably author): wood, covered with a thin velvet.
The artist is unknown, the time of writing (presumably) the end of 19 - beginning of 20 century. The picture used to be with relatives in the city of Leningrad, and before that lived in the Saratov province. Painting stretched on the old sliding professional stretcher. Used medium-canvas direct dense weave, causing the soil by hand. By the nature of the destruction of the paint layer and the presence of a layer of paint on a different color can be assumed that this pattern is written on top of another picture.
At the 1-st photo shows a picture without a frame after its purification, the 3rd picture in a picture frame before beginning work on its restoration. If you need more pieces, I can lay out further.
I would be grateful for any, even the most unexpected opinion or advice in which direction to search for the artist.
Dmitry.

Nobody get any ideas about painting?

Work amateur artist, his time, that which you have written.

In the 2nd picture on the back of the canvas clearly appear the outlines of a completely
distinguishable according to a design (topography) of the first serious varianta.Trebuetsya
survey of paintings in infrokrasnom variante.Chem devil does not indulge in the original
letter starting SOMEONE and O-GO-GO (!) with what (!) name will be!
Take the time to do it, Dmitri. "Who is looking for, will always find." This is perhaps
central tenet of any aspirant, be he a collector with experience or
novice lyubitelem.Udachi!

These paintings were given to cook boyfriend. Sliding stretcher nothing said but before you restore make X-rays. Maybe a "cook's joy" and find something more interesting.

Dear experts!
'll Show on the X-ray study painting. I turned on the issue at the Research Institute of restoration. They advised me not to do X-rays of this work, as the lower layers of paint paintings homogeneous, similar properties to the paint of the upper layer. In this case, X-ray may not give anything. By the way there suggested that the entire bottom are 2 pictures, one under another.
So my question is not encountered anyone with such a complex case. Maybe someone will prompt Moscow to seek better not to waste your time, money and not in vain to pull the work. For one thing I will grateful for references to scientific articles and books on the subject.
Thank you.

Traffic picture
 

Decided to bring a photo traffic pattern after processing it in Photoshop. Source file RAW-format. Produced increase image contrast in general and individual lines (enhanced brightness of some of the light areas and further reduced - darker). Image mirrored, to simulate the view from the front of the picture, as if through a layer of paint. At the end of the transform in b /w, because true colors with this approach have no meaning.
I would like to know the opinion of experts about the method invented by my research. It is based on the assumption that the paint from the lower layer of the picture stood out stronger on the back surface of the canvas, with more than the upper. Can I assume that in this case, X-rays will give better results?
Does the reduced picture anything to understand the picture itself?

Of course, this picture gives the smallest idea of this picture.
Modest pezazh with a house on the river (lake, pond). But in the most
modest visual tools can be hidden masterpiece.
Why do not advise rengentografiyu not quite ponyatno.Esli at
detailed examination of the paint layer pattern is determined that the upper layers
colors lie directly on the homogeneous lower layer of oil, then
Late withdrawal layer almost nevozmozhno.No if between the colorful layers
found a layer of top coat, the separation is not a distinct
complexity for the restorer-professionala.Kstati on old works
almost 100 per cent presence laka.S covering of the picture should work.
Be bold, with good luck!.
