Take a good look at the paintings you own but can't identify. Fortunes are being found these days. In Italy a Paul Gauguin painting and a Pierre Bonnard self-portrait hanging in a kitchen for 40 years were identified as stolen from a London residence in 1970. A retired Italian factory worker, owner of the paintings, bought them 40 years ago at an auction of items abandoned on a train. He said he is happy to have had the pleasure of living with them and was "proud" of his taste in art. Authorities are checking to see if he bought the paintings in good faith. The artworks will probably be sold.
