Here is an insouciant pose that could be taken from the book.
"What the Earl saw was a graceful, childish figure in a black velvet suit, with a lace collar, and with lovelocks waving about the handsome, manly little face, whose eyes met his with a look of innocent good-fellowship." (Little Lord Fauntleroy)For comparison Gainsborough's Blue Boy.
Or Goya's "Blue Boy", actually a rarely seen painting of Infante Don Luis Maria.
Or Linus' dark Blue boy.
Great works of art all of them.
