Wigs on the Green has dated this piece to the 18th Century.
This was published as an engraving around 1774.

Set with a verre eglomisé mount, the portrait is presented in a traditional papier-mâché frame with a decorative surround.
The portrait is attributed to John Keyse Sherwin who was born in Chichester in 1751 to Francis and Martha Sherwin. Despite humble origins - his father was a labourer - Sherwin was sponsored to go up to London to study under master engraver Bartolozzi. He went on to exhibit portraits at the Royal Academy between 1774 and 1784. Despite success both as an engraver and as an artist, Sherwin was reputed to have been a drinker and a gambler, vices which inevitably resulted in poverty and contributed to his premature death at the age of 39.
