I am no art historian nor am I an art scholar, but I know what I like when I see it. This style of Picasso's paintings is something I happen to like. The simplicity of a few strong black lines defining a the features of a person, in conjunction with the subtle use of color creates a visually striking imagine that makes you want to stare at it. The image on top is "Madame Picasso" was taken by me at the National Gallery of Art in DC. The one below, which hangs in the BMA, is "Mother and Child". The image is not my own, and comes from here.
Here are some more photos from the National Gallery. Taking pictures of art really makes you connect and see the art on a different level. If you have never tried it, I suggest that you do. A macro lens certainly helps you to get up close and personal (they would be a lot less fuzzy, if I toted around a tripod...but who wants to)
