This is a loveseat I found on C/L Boston. It is a H & M Vintage or so they say Chesterfield loveseat. It has no rips, tears, missing buttons, and is pretty with light wear from over time. I have a few questions. What is it worth? Can you ell from the pictures what grade leather this is, what color, and how do you tell if its vintage. Does being vintage make it worth more? Thank you very kindly for your expert opinion.
