Here's something I found for you today. Rather charming, but you can't help thinking she is more concerned with smiling sweetly at the painter than with whatever is on the canvas. But maybe she is painting the painter? Here's what it said about him on the site I found him on:
Max Nonnenbruch (1857-1922)
A painter of striking seductiveness of style is Max Nonnenbruch, of Munich. After winning recognition by his earlier works of domestic genre, he devoted himself almost entirely to idyllic and semi-classical subjects, akin in feeling to "The Favorite," in which he found the true direction of his talent, and by which he is represented in the greatest private collections of Germany.
