This charming painting is a copy of a portrait of Charles Biggs Calmady's children, which was exhibited by Sir Thomas Lawrence at the Royal Academy in London in 1824. It quickly became famous and was reproduced as an engraving in 1832. It depicts the collector's two daughters: Emily, the brunette, who was aged five; and Laura-Anne, the blonde, who was then still a baby.
This double portrait is striking for its crisp colours and the quality of the workmanship. It is a copy dating from the period, but differs from the original (now held at the Metropolitan Museum of Art in New York) as the copyist did not reproduce little Laura's hand above the head of her sister. However, this hand can be seen in another copy of Lawrence's painting – an English miniature on ivory dating from the second half of the 19th century, which is also held at the Musée Cognacq-Jay.
