The miniature is signed, inscribed ‘Painted from life’ and dated 1836 on the reverse.
The artist trained with his father, the noted enamel painter Henry Bone (1755-1834), but then worked for some years in oils. However, he later reverted to enamels and became enamel painter to Queen Victoria and Prince Albert.
