A Japanese author is appealing for help after losing her life's work following a visit to Chichester.
Tomoyo Nakao had collected around 150 pictures of those who fought the Japanese in Burma during World War Two.
Many of those pictures were taken of Portsmouth veterans, whom Tomoyo had interviewed during the mid-90s.
She said she is devastated by the loss, and hopes someone may have picked them up when she left them on a train during her journey from Chichester to Oxford, via Southampton, on November 13.
She said: 'Many of the people in the photographs have now passed away, so they were really irreplaceable.'
The photos were in a carrier bag.
Tomoyo is now back in Japan, but is offering a 1,000 reward for anyone who finds the pictures. They should email firstname.lastname@example.org, call 078 8224 0274 or 020 8904 1886.
