Earning a Living
Girl with a Watering Can, 1876 by Pierre Auguste Renoir.
Renoir painted this young girl to attract people and some portrait business. Portraiture was the 19th century artist's bread and butter.
Blue and White Vases
The Daughters of Edward Darley Boit, 1882 by John Singer Sargent, MFA Boston.
Sargent's portraits of children are among his most expressive. It must have been nice for him to work with subjects who would have probably been less vain than the adults (although I am sure a few of them were looking over his shoulder).
