This is a copy, or independent work, if the latter, who can be an author? (Unsigned)


Second, the initials of the artist marina.Est ..

Thanks in advance.

Andrey79, picture quality can not answer your questions.

With the possible exception of the second scene with sailboat.
This is an amateur art, artistic value is not.

By the way, the painting depicts a fishing boat as the mast is an international code flag marine signal Dad (P, Papa), which means: "My network upon an obstruction."

In the harbor the same flag means that the entire team must be on board.

The first picture - the type of Soviet art of the 1950s, a generation born in the year 1905-1917 (the so-called Lost Generation).


The second picture - the furnace.

Andrey79, frame in good condition and not sealed with bronze paint.

This is not a copy.
At the back there are any inscriptions, seals, stamps, etc.?
Not a bad author's paintings.

Unfortunately at the back pictures in general there is no Dop.informatsiya.
