'll Show on the examination
 

I want to buy one now. Expertise on it there. There is now such an explanatory note made in the restoration workshops of the Peter Ax. I understand that this is not expertise, but better something than nothing. Has anyone encountered similar?

SergeiSK, I just sold a picture without examination, but with a passport restoration of the monument of history and culture (dvizhemogo) the results of research foundations, soil and paint (him.analiz). All this was a good volume with a brochure and was impressed the buyer.
It is only then he was doing due diligence and showed these restoration bumagi.I they reacted well to them, organization is doing a major restoration.
But on one leaf, I, honestly, now is seen, but I think, and such byvayut.Chego only and not uvidesh!

Cyril Syzransky,
This is just opinion restorer, who was involved in this picture. Plus there is still the most macro picture and signature. I probably still buy ...

SergeiSK, Here is attributed paintings, with a clear signature look (may be useful)
