jlb684: Being a bit biased, my son is my favorite artist! (He's in post-grad art school now, has had a number of shows and sold some of his work. Yes, I'm a proud Mom, but he does indeed have a gift).
Otherwise, I am most fond of Renoir, Van Gogh, and Monet. As for sculptures, I love the work of Praxiteles and Michelangelo.
What a wonderful gift you gave your son. My mother said my sculptures were trash. Once when they were in the local museum did she call them art.
