According to the history of Malmesbury I have . In AD930 King Athelstan called on the men of Malmesbury to defend the town from another raid from the Daines. Upon their success he gratefully rewarded them 700 acres of common land, known as King's Heath to the southwest of town. So the picture must have been taken in 1930 as it said was bequeathed to Malmesbury by King Atlelstan one 1000 years ago.
