Help identify the author of this picture, presumably Yushkov Fedor Osipovich
Thanks in advance

And why "Ostapovich?
Or maybe "Osipovich? Fedor Osipovich Yushkov?

Yes, you are right, "Osipovich. What do you think - is he? Or are there alternatives? We filed the request and at Sotheby's, and Christian, and then decided to ask.

And what you say there?
You need a timing "to request", there are two works by F. O. Yushkova - "The Cabinet Vl. Kn. Olga Nikolaevna of the Winter Palace" and "Gothic hall of the Winter Palace.
They will be able to compare.
What is the size of your things?

They said that if possible call the author, the approximate cost and will stand or not.
Complicated by the fact that his works are very few survived.
Yushkov is tentatively ("Yush" incomplete "f" as a sword, said to belong to the military. Only the "C" certainly contributes.
And that could mean horizontal ticks at the end, I read about them somewhere without mentioning details.
Size 60.5 cm x 45.5 cm unframed.
And can you tell me where the catalog of signatures can be found?

So many stroke replaced the letter "Kommersant" at the end of last names.

"C"? I think it is "O".

You should go at the party Amateur, it is special for the signatures and knows all sorts of sites where they can see:

This will display "? And this is how? How do you provide them with the work physically?

And this may cause problems?
If yes, what for example?
From the pictures the first time cause I have bought intuitive feeling thing.
And now I would like to understand as possible.
Thanks in advance.

By Fyodor Yushkov losifovich (Osipovich) Yushkova son Joseph I. (1788-1849), sculptor-lover, a native of St. Petersburg, this picture has nothing to do.
Known picture of F. O. Yushkova "boarding. One of the British naval war."
There clearly is a signature on the right in the corner. From the above, nothing in common.
The capital letter F, for information, written at the time and the military, too :) O as a horizontal line in the middle.
