"The Blue Boy" by Thomas Gainsborough (1727-1788)
"The Blue Boy" painting was actually a portrait of Jonathan Buttall the son of a wealthy hardware merchant, painted in 1770. It is thought to be a study on 17Th century clothing, and also done in honor of Anthony Van Dyck portrait of Charles II as a boy.
As I posted earlier "The Blue Boy" is on display at "The Huntington" in San Marino, California.
My mother loved both of the paintings of "The Blue Boy" and "Pinkie", they were always on display in our formal living room. These paintings went along with her love for french provincial furniture.
