To decrypt the signature...
 

Colleagues, please help to decipher the author ? With me a bottle of brandy" interest in sports, can't read...Well, who is the author ?

Beta[ей] CDIS[…]

Signed clearly belongs to a foreign artist...

Colleagues, with me present !

it is a pity that You did not show the whole picture. I read this signature, as: cop Cohn, ie copied Cohn

Where does the word "copied" ? there is no such clearly...probably reads like the author... ( author's work ) :)

all worthless - from "there"...:) In the copies of paintings, made by European artists, sometimes there is a reduction (cop) i.e. copied... Copy - painting too, but unfortunately - not the author's work :)

Honestly not veronicah that resembled a COP. But I think really it would be easier when looking at the picture itself. Then, though the period would have been clearer.

apparently the last quarter of the 19th century.
And we ought to take a look.... the important level of painting.
If high, then there is hope for the quest.
If low, perhaps the artist is not registered in databases.
In this situation, at least read it, don't read though......

And for me, so late squiggle uncertain, so typeKalya Malle".
