The show, The Lost Collection, which is currently running at the agency's London HQ in Hoxton Square, is a collection of art left on London's Tube, buses and trains.
One person reunited with his lost work was Regis Gautier Cochefert, a student at Wimbledon School of Art (and now the head of art at the Paul Hamlyn Foundation), who left his final-year project on the Tube. He saw the work in the press and contacted the agency. It was of great sentimental value as it was a project based on his father, who had died before it was finished.
Also, friends of Ana De Lima, an artist who lives in Barcelona, spotted a photo of her picture in a London Evening Standard article and she got her work back. Diary loves a happy ending.
