If you're enjoying a beachside holiday this summer you should keep your eyes peeled for a mysterious beach from a 1920s painting.
Christchurch City Gallery purchased "Sentinels" by Thames painter Rhona Haszard earlier this month, and it depicts a balmy seaside scene.
But the gallery's staff aren't sure where it was painted - and they'd quite like to know.
Tim Jones is Christchurch Art Gallery's reference librarian. He speaks to Corin Dann.
