Anyone know what this Antique Sofa is worth?

Hi there --
This sofa was bought by my grandparents at an estate sale (probably in the 1940s), and has been in my family for decades. I need to sell it now, and have no idea what type it and how much it is worth. It is slightly off-white now, but could probably be cleaned. Otherwise, it is in good condition. Can anyone shed some light on this for me? Thanks!
