I wonder what kind of picture
 

Dear experts, a long time I hung a painting, found her brother in the attic of his grandmother.
So I would like to know the author of this picture.
I apologize in advance for the quality of the photos.
I'll try to do better.

Do you copy the work of Ivan Aivazovsky.

View of the sea at night.
22h30 1873 Oil on canvas.

Astrakhan Picture Gallery im.P.M.Dogadina

I fully agree with what was written above , it is really a copy of the picture Ivan Aivazovsky "View of the Sea at night ," another name for " Seascape with Moon" ( 22h30 ) 1873 . I shall only add that earlier work belonged A.N.Bahmetevoy and it was donated to the Astrakhan picture gallery of them . P.M.Dogadina . Inventory number 7468 . But the picture that showed the Pecheneg, it is a reproduction of Aivazovsky " The Bay of Naples at night ," another name for " Moonlit Night on the Bay of Naples " ( 42h28 ) 1895 is in the State Tretyakov Gallery . (Dar professor Sarkizova - Serazini )

Thank you very much!

There is also a sketch to work "night view of the sea" with an interesting tag on the back.
For authorship of Aivazovsky, unfortunately, I can not vouch.

Ahem.
Etude - when from life.
It's not like that.

And the way is really not very much like IK

Etude - it's just a preparatory sketch for the future work.

I could not agree with the findings of the masters of that Study - is a preparatory sketch for the future work. I called etude shown by their signatures on the label . As you know, I.Ayvazovsky in his work done without sketches. By his own admission, Aivazovsky sketched the story of the future picture on a piece of paper and with the fugitive pattern set to work on the canvas . And what passes as sketches, inundating the market , in all probability , is the failure to copy the seascape .

it turns out that "the study is a sketch ?" - What did they differ? In my opinion, a sketch - this how-to "draft " , a preparatory sketch of the whole work , and study - a " rough draft " outline what its parts ?

It is now believed that the sketch - it's just such an Exercise in the open air , the training is not specific to future work , and some scales for the artist , and a sketch - preparatory work for the specific ideas, the painting , which the author comes up , wants to create.
But , actually , it's the same thing - sketch, sketch.
