As a watercolour painter, Vosper began exhibiting his work in local art galleries throughout England, but also at the Paris Salon and the Royal Academy.

The picture featured regularly in Welsh-language publications, including in Y Ford Gron ('The Round Table') in 1933, as print copies sold via the Urdd in 1937, and in the Cymru Fydd calendar in the 1950s.

In 1942 it was described by Yr Aelwyd ('The Hearth') as "one of the most beautiful pictures of the religious life of Wales in old times .."[2] The painting gained notoriety when it was believed that the face of the devil could be seen in the folds of Siân Owen's shawl.

The painting also became extremely popular in Wales, offering to a population which was rapidly becoming industrialised a reminder of a rural past[5] and a close connection to the Nonconformist religious background of the country.

[6] The work is currently exhibited at the Lady Lever Art Gallery at Port Sunlight in Merseyside, though there have been several request for the painting to be moved permanently to a Welsh museum.
