Who painted this famous painting?
This famous painting is called "The Blue Boy". It was painted by Sir Thomas Gainsborough. It is now located in the Huntington Library, San Marino, California.
It is a historical costume study as well as a portrait. The youth in his 17th-century apparel is regarded as Gainsborough's homage to Anthony van Dyck, and in particular is very close to Van Dyck's portrait of Charles II as a boy.
This very painting is a great representation of Thomas Gainsborough's style: all his works were painted in light colors and with easy strokes. The unique play of shadow and light is also present. He was also a talented landscape painter, that's why the artist paid a lot of attention to the backgrounds of his portraits, as we can see in this picture.
In a move that caused a public outcry in Britain, it was sold in 1922 to the American railway pioneer Henry Edwards Huntington for $728,800 (£182,200), a then-record price for any painting (which would be over $8.5 million in 2014).
