Thank you very much for your answers . It was important to hear the views of disinterested parties . During the restoration there was another question related to possible duplication of edges .
As options are:
Duplicate edges and to achieve the perfect tension of the canvas .
Do not duplicate , and leave some strain relief .

Which is preferable ?
Do not scare potential buyers duplication .

As a buyer I can say that I am personally bringing canvases in order ( including overlapping edges ) are not deterred , and the only attraction. As a minimum , this means that after purchasing the work you already do not have " piles " of restoration, to carry to a job (and they are big and awkward to carry ), etc.
One point - if you plan to make the expertise - it is better to do it before the restoration . And yet it is desirable to keep photographs of works before the restoration .

One thing - if you plan on making expertise - better do it before the restoration . And yet it is desirable to keep photographs of works before the restoration .
     

Attribution carried out, also have the original picture before restoration work .
And how important it is to have documentary evidence of the works ( restoration card, passport) ?

And how important it is to have documentary evidence of the works ( restoration card, passport) ?

It is so important - as far as You is important : >
Better to have , of course , especially given the value works .
By the way , making a correct restoration of the passport respectable " heavier " the cost of service restoration .
In general - the last word is always the client .

in "Russian" ill-advised to not ...

In the Russian Museum are good conservators.

Trust them, not bad advice.

Canning must without fail. It can not even be discussed. Any item after restoration (no matter how the restoration was complete-partial) must be preserved.

As correctly pointed out above, conservation of paintings held reversible varnish, lacquer that is easy to remove if necessary in the future.

The paint layer under the paint will inevitably-by-step to take (absorb) the dust from the air. If conservation is, the dust enters the lacquer film and dirt in the future be removed easily with a top layer of lacquer. Without the varnish film dust "eats" in the paint layer. And the dust - neizbzhna. And the collector's home and we have a restoration workshop and a museum on display.


That simple little illustration.



And the scheme is made up not of "old" painting, and in general for any oil /canvas. That is pollution from the air, I see everywhere. It is strange that you are considering without conservation is a mandatory part of the intervention in the work of art.

And pollution is everywhere and always, the only question the admissibility of their volume. Sorry for copyrights on the scheme - a necessary measure.
