"Bernard Boutet de Monvel executes Elvire de Brissac's portrait in 1946. The artist first portrayed the girl sitting in the grass (see lot 247 for a preparatory drawing), and then this ravishing profile portrait, kept for himself. See lots 20 and 22 for portraits of her parents." http://www.sothebys.com/en/auctions/ecatalogue/2016/collection-boutet-de-monvel-pf1639/lot.23.html
