A centuries-old painting by legendary Suffolk artist John Constable is going under the hammer at auction.
The 200-year-old oil sketch by landscape painter Constable had been lost for more than 40 years.
It was discovered in a private collection in Guernsey and will now go under the hammer at Martel Maides Auctions on the island on Thursday, September 21.
Constable was born in Suffolk and is known for revolutionising the genre of landscape painting with his pictures of Dedham Vale, near the border with Essex.
Jonathan Voak, paintings specialist at Martel Maides Auctions, said of the piece: "The re-emergence of this oil sketch will make an important contribution towards establishing the chronology of Constable's body of work".
