Old portraits

Who is the author of the portrait? What is the date? What country?

 

Why don't we start by you telling us what you know about them. In what part of the world did you find them and what were you told about them?

These portraits are in Russia. It is suggested that they may have been painted by the Dutch and that they are from the 17th century.
but I don't think they are that old?

 

Given one is signed with the surname Walter and dated 1872, I think that unlikely. (The inexpensive, modern frames do them no favors, by way.)

Is that’s a wax seal? Maybe marked as part of someone’s collection?
