An affectionate portrait by Augustus Edwin John of his daughter Gwyneth Johnstone is an eye-catching lot in the Cheffins Fine Sale, held on Wednesday 12th June and Thursday 13th June.

The portrait was painted when Gwyneth was 17 during a brief period when she shared a London studio flat with her father, one of the most prominent British artists of the 20th Century, along with his sister, Gwen John.

Gwyneth would go on to become a very talented artist in her own right and this portrait was mentioned in her obituary in The Times in 2010, which described it: "John painted her portrait, in a fresh, characteristically freely-stated and clearly affectionate study of the beautiful young woman who gazes quizzically out at him, and us, from beneath her mop of auburn hair".

She was brought up between London and Norfolk by her mother, the pianist Nora Brownsword, who had met Augustus John when she posed for him shortly before the First World War.

Gwyneth, who studied at the Slade School between 1933 and 1938, is best remembered for her colourful Mediterranean landscapes painted when she travelled Europe and it was the scenery of the South of France and Spain which most inspired her.

She lived her later years in her beloved Norfolk.
