Oil Portrait Pianting of a Women with Collar

A school oil portrait done on canvas; un-stretched and newly matted and framed in an antique gilded frame. frame has visible age related wear noted throughout as well as minor age related wear to the portrait itself. This was part of a 7 portrait lot and is labeled on versa 7 (of 7). Artist is unknown and it is unsigned. I suspect age to be late 1800's to mid 1900's, though the painting is undated and actual date is unknown. some photos include the portrait before framing.
