A small booklet containing the terms of the agreement made between the North Wales Slate Quarries Association and the Transport and General Workers' Union regarding working conditions and wages. The exact date of the booklet is unknown, but it is believed to have been produced during the 1960s. The booklet originally belonged to Mr Alun Roberts, a quarryman at Dinorwig Quarry, who was an active member of the North Wales Quarrymen's Union.
