Self-portraits by the artist Francis Bacon are set to go on display for the first time after being rediscovered in a private collection. In June, they will be available to view at Sotheby's in London.
Experts knew of the paintings' existence but were unsure who had bought them after their completion around forty years ago. After they have been on display in New York and London they will be auctioned off. Each painting is expected to fetch £15 million.
