It was the smaller of two 'heads' allegedly stolen from Whistler and bought by John James Cowan (1846-1936) in 1900 (see Alice Butt (2) [YMSM 438]). Cowan described it as an upright panel, 'Study of Model head & shoulders - looks like "La petite souris" you had at Knightsbridge. grey dress dark background & lovely bits of gold shining through - being the natural colour of the panel.' 1 The painting to which he compared it is Grey and Silver: La Petite Souris [YMSM 502].
