IT'S a mystery that nobody has been able to solve, not even the dedicated staff at the Australian War Memorial.
A photograph of soldiers from the First World War has been discovered in Coffs Harbour Regional Museum's collection and local knowledge is being sought to help find out the details.
What is known is that the metre long panoramic shot of a large group of Australian soldiers was taken in 1916 probably at Salisbury in England.
Museum curator/director Dr Leigh Summers said that that is where everyone hits a dead end as far as information goes.
"Sadly that is all we know as we have no information on who gave the photograph to the museum or its history," Dr Summers said.
"We contacted the Australian War Memorial's curators to see if they could shed any light on who the soldiers were but we drew a blank. However, they have since added the image to the National Collection."
