Watch Jonathan Stuart, son of famed Saturday Evening Post art editor Kenneth Stuart, as he discusses the creative collaboration between his father and Norman Rockwell who once said, "Everything I am, everything I have ever done, everything I hope to be, I owe to Ken." Through the course of their long friendship, Rockwell gave to Stuart what has become a collection of iconic American paintings, including Saying Grace, Walking to Church and The Gossips all of which will be offered in Sotheby’s American Art auction on 4 December 2013.
