Portrait of a lady, presumed to be Sarah, wife of Charles Johnstone of Pontefract, head and shoulders, in white with red-lined shawl, in a painted oval stone cartouche indistinctly signed or inscribed lower right on the stone cartouche oil on canvas 75 x 62cm Footnote: The sitter was the great-grandmother of John Gardner of Chatteris, who died in 1804. Provenance: By descent from the sitter to the Gardners of the Manor House, Chatteris, until removed in 1908 by Algernon Dunn Gardner (1853-1929), great-grandfather of the present owner, to Denston. Condition report: Oil on canvas which has been lined, the picture is in plane with good tension. There are a few small losses in the background above the sitter's head. Old retouchings to the left of the sitter have darkened. The varnish is dull, yellowed and collected in the texture of the paint surface creating a slightly mottled effect to tee flesh tones. There is a light layer of surface dust. The frame is in a good condition.
