'When duty calls'

Of ‘British Manufacture’, according to information printed on the reverse, this postcard was part of the ‘Savoy Series’, ‘No. 101’, published by ‘Brown & Calder, London’. The text that accompanies the image (by ‘J C Biggar’ [?]) reads: ‘When Duty Calls’, ‘A Fond Farewell.’ A poem is printed across the mother’s apron, ‘Farewell dear one / At duty’s call / With Britain’s manhood waking / I leave my home and / You my all / Although our hearts / Are breaking / God grant my prayers / May not be vain / For you till I come / home again.’
