Curious portrait Bukowskis in Stockholm

[uriart]

The hypothesis is really interesting!
And like any hypothesis is the place to be!
In my opinion is represented not by a Russian woman. It is quite a Swede or other inozemka. But Russian, I in it I find nothing.
Although, here are two portraits by Ivan Nikitin.
In oval Princes Anna Petrovna.
The second portrait Praskovia Ivanovna, a niece of Peter the First.
A small detail!
In the portraits of women are not depicted hands. Although one of the men's "Count Golovkin" hand shows. So this way of writing hands quite different, though his hands are different: male and female. Pity can not be copied and placed on the site
And.
Portrait of Bukowski. The woman is clearly not the first youth. It has long been over thirty, and perhaps the beginning of 40 years
