Just who are these two First World War soldiers with their youthful beaming smiles?
Their photograph is a centre piece of Birmingham Museum's First World War exhibition.
But who they are is a mystery.
The exhibition tells the story of Birmingham in the First World War through the soldiers who fought it and their belongings which still survive.
Many fought in the Birmingham Pals - the Birmingham Battalions of the the Royal Warwickshire Regiment. But some are the unknown soldiers.
Jo-Ann Curtis is from the Birmingham Museum:
The exhibition has many artefacts - including a genuine officer's map case. Complete with the map of the Front Line.
There's also a genuine uniform worn by a soldier of the Royal Warwickshire Regiment in the First World War.
He survived - but he remains one of the unknown soldiers.
