'Coombes and Alexander each had a passion to show the real life of coalmining communities to a wide public, Coombes through words and Alexander through pictures. Coalmining was veiled more opaquely than almost any other sector from the view of educated people and metropolitan elites. Many of its particularities, literally hidden below ground, were unimaginable to outsiders who had never contemplated what it might be like to spend the day in darkness, to labour in a space no higher than a dining chair, to bear the daily crush of fear that a husband or father might not come home from work, or to suffer injustices of wage cuts, industrial disease and injury.'
