If not a secret, write a few words why?

It is not always inclined to believe the press and Internet sites, information often is not fully reliable.
Perhaps someone will comment on the following:

Tretyakov Art historian Vladimir Petrov opposed reform expert case, although he once admitted that the accident assured as true about twenty imitations. Colleagues Petrova, who asked not to reveal their names, claim that "ninety percent of the examinations he did on his own behalf and not on the letterhead of the museum"

Vivian, and then comment on that?
Yes, VA Petrov gave private expert opinion. Sometimes on the back of photographs and paintings. He he is a man well known and public, his expertise is always possible to show him and ascertain its authenticity. And with ekspertiruemoy work.

The point of this topic, in principle, not experts, but in the work.

Examination of course examination, but that's my particular case. Recently looking theme antique shop , nadknulsya one job that once seemed to me then than svoim.t.e learned author of the study , and the manner and as an object on which it is made , in general everything. After reading the price of half a million dollars, do not even know what to do? Cast a shadow over the work that costs a lot of money , having no expertise.

And the work is weak, with 100%European painter, and expertise levaya.Proverka the registration number will lead to an entirely different work, and Petrov is not obsolyutno prichem.S HC ..
