In my opinion, it's really 1930, but not expensive and is not anti-tank ditch.

Almost certain that it is laying some of the industrial enterprises - factories, Magnitogorsk (?).

Johanna, the family owners of the Urals is not connected?

Look: this is clearly the free labor of free people. Moreover, work, perhaps a holiday. And the color of the picture, and free the girl on the left resting posture, and even some features of talk about it.

Again: a red scarf girl refers to 1930.

Pimp that rolls one of the characters - such as the times were in the 1930s, the movies shown.

The composition shown: for anti-tank ditch too many men, and all the work once the war is not associated (for me, at least). And zekami, by the way, too.

All dressed up in a rural, women in headscarves deaf, but light (holiday), and in bright skirts, men are also quite vividly dressed, and only resting a girl - in the pants.

For completeness, lacking only the slogans on the lobster, but I think 1) they do not fit into the challenges in front of the artist, 2) in the sketch, you can do without them, and 3) what the slogans in the pit?

All of this is very reminiscent of a scene from a favorite plant "Evdokia" - remember this wonderful movie?

And in style, I would say, much closer to the avant-garde (look, for example, sunspot - a luxurious) than to socialist realism.

To be fair: in favor of the version of Igor Guryev, in my opinion, says only one figure - on top of the pit - the right, but it is so uncertain, that could not make out - or a bodyguard, for example, the foreman. Rather - the second, or even party worker ...

In general, as a result of my reasoning is it that as an author to look for a young artist in the recent past is not alien to the avant-garde, which in 1930 went on a business trip in the construction of the future industrial giant. The name of this artist - Legion <! - ~ 2 ~ ->. Probably, you have to look directories reporting exhibitions of artists, business travelers to areas of industrial and collective farms (1931 and 1932). And in 1934 was reporting exhibition of paintings, seconded by the CPC of the RSFSR, Commissariat, "Vsekohudozhnikom" MOSSKH and the Soviet Union in 1933. Maybe there's something to be revealed?
