Jack White is one of those “I’m tellin’ it like it is” guys from Texas. His wife, as he will tell you, is an incredibly successful artist. Together, they sell a lot of her paintings.
I’ve read a lot of his articles in Art Calendar and he presents a lot of interesting and new ideas about how to sell art. He’s one of those authors who can really get you off your chair and into action.
You can buy his ebooks here.
