sought-after ! Antique late 1700's to early 1800's Sir Joshua Reynolds antique framed print <3

Dates from somewhere in between the late 1700's to the early 1800's, the print is of the famous Scottish surgeon and scientist John Hunter (1728-1793) the original which this was copied from was made by the famous English artist Sir Joshua Reynolds, there's some antique paper and writing on the back (it's really fragile so I ended up covering it with acid at no charge plastic wrap for the time being to protect what's left), still has it's original metal wire hanger on the back, I got this years ago at an antique store was told who it was and an estimate of it's age, and while it's in good condition considering it's over 200+ years old it still does have a good bit of wear and tear from age and handling over the centuries (a lot of damage to the frame, parts missing, wooden planks on the back are loose, stains, scratches, etc it definitely needs some TLC).
