An unrecognised painting sold for more than £81,000 at auction.
'A View of London from Greenwich with St Paul's and the Isle of Dogs in the Distance' by Susanna Drury was discovered in a house in Richmond.
Jeremy Lamond, from Salisbury’s Woolley and Wallis, oversaw the sale.
The gallery is located above the library.
