Here, I've reworked one of my Sony Reader drawings/studies in mixed media on paper.
A Google image search can yield loads of portraits, from all eras, of "The Painter's Wife". One of my favourite paintings of this type is a portrait by Roaul Dufy (below) of his wife who he has painted sitting at a table with a brightly covered cloth against a brilliant blue ground. The original painting is in the Musée des beaux arts, Nice.
