I Socialist Realism (in the classic version, joyful pioneers, workers, leaders) do not like it in principle. So my opinion - biased. I believe that no investment contemplate in this kind of art and this painting (first post) in particular - no.
Investment contemplate as an attribute of time (along with teapots, phonographs, and other helmet) probably is, but small.

Enjoy the historical picture of the 1920's.
 

But the picture bought from a resident of the village, he live in the Tambov region.

And what, dear colleagues, in your opinion, the fate of such an artifact that has no (again, in your opinion) to attract investment.

The movies can be removed .. in the theater (like Entourage) to work .. "Note the time" (in other words) to bring .. Or at an exhibition of relevant ... (and spirit level)

Investment prospects, I think, no, but in historical terms a definite value, of course. For local history museum, or for those (possibly future) historians, who will study the history of the commune and the fate of its inhabitants. About 20 years ago, it would be absolutely futile, but now it can be.

I just now thought that he wrote it, of course, a local amateur artist. And certainly tried to convey a portrait likeness. Maybe someday the history of this municipality must write, and then shown in this picture, perhaps will gain their names.

Theoretically, purely theoretically, could be of interest for people of those territories, or from families who once lived there.
But I think all these Communards in 5-6 years after the arrival of Shaw under the knife admitted.
We must also remember those who organized this commune, there a some "foreigners" spyware and composed.
