Thank you all!
And I went to the St. Petersburg antique house, where they deliberated on the type of the Hermitage and decided that it Freret!
Here's what to do I do not know where else to apply, and how to identify the author .....
<! - ~ 3 ~ -> <! - ~ 9 ~ ->

Has a portrait of how the work of French artist, or options?
 
For example, I read a Bogatsky (he was a portrait painter in the mid-19th century) or the possible options.

Anything is possible .....
But it is known that the picture has been taken from Germany during and after the war.
