A book in braille produced by prisoners which tells the story of the Ulster Division has been presented to the Somme Museum in Newtownards.
A group of prisoners in the braille unit at Maghaberry prison have spent the last year producing a total of eight volumes, which include appendices, an index and maps.
Head of the Northern Ireland Prison Service, Ronnie Armour, said: "This is an excellent example of how we are supporting people to change and make a real difference to their lives through rehabilitative activities.
Mark Mooney, braille instructor at the prison, said: "It's been challenging for the prisoners, but they have shown incredible commitment to see it through to the end."
Carol Walker, director of the Somme Association, said: "I have no doubt the book will be appreciated by the many visually impaired groups who visit the museum."
