Painting Vinogradova

[Elena_R]

Dear experts, need help and advice.
According inherited pattern SA Vinogradov, located in my family since the late 20's, may, with the 30-ies. Not restored, not published. Size approximately 38h58.
Give that it be done to sell, because we can not maintain it (as early as 1 square centimeter showered), and judges not.
Actually, the topic has already studied a little bit.
First, suppose to give it up for examination in the Russian Museum (St. Petersburg because). And then what? Board? Once at the auction? Somehow the impression that the people "from the street" does not get there.
Everyone who would vote, thanks in advance. : shy:
