Pong, I worship the man. He is my favorite artist aside from Van Dyck and Michelangelo. His colors and tones in his paintings are just incredible. If you have a chance to be face to face with one of his paintings, I am sure your jaw will drop. Mine does every time. I am very lucky to have a Bouguereau here in the Montreal Museum of Fine Arts. Also, there is an excellent study of a girl's head in Toronto, Ontario. (A six-hour drive.)
I just discovered another Bouguereau site here in the Forum last night. It is very complete. You can find drawings, paintings, and oil sketches. Check it out.
