Found portraits as Franz Karl and Sophie:

But I am sure it isn't them. It looks to me like some other Habsburg pair, but don't know which one.

Any thoughts?

I totally agree that the subjects of the portraits are definitely NOT Archduke Franz Karl and Archduchess Sophie. However, I have no idea who they might be,

Weel, that is obvious but who could it be?

I have sense that the pair is also from the Habsburg family, just couldn't define around which year the portraits were executed.

Anyone?
