HUNDREDS of unclaimed portraits of World War I Diggers taken in London before they left to fight on the Western Front have been added to the National Archives collection, according to the latest newsletter from the Northern Territory Genealogical Society secretary , June Tomlinson, in the UK doing research . The 500 black and white portraits were found among 1600 photographs of Allied soldiers collected by the Imperial War Museum, London, after the war. The 500 are significant because they are not known to exist anywhere else, mainly because soldiers never returned from battle to collect them.
