The image illustrated is one of a pair of a brother and sister, William and Sarah Kendall. They are full length portraits set in English country landscapes and although not signed by the artist they were painted in 1791. They have not been relined and they retain their original frames.
Her portrait in which she holds a green bird in her hand appears completely original, while he in his portrait is holding a prayer book and standing beneath a sky that has been over-painted. This is something that could be quite easily corrected but as they are such charming things I have decided to overlook this imperfection.
