Simply that is a Picasso that you can actually look at... unlike those ridiculous "Cubism" monstrosities.
FWIW, a lot of Picasso's representative stuff has a presence to it that doesn't translate well to scanning and reproduction. See one of his in a gallery among other paintings and it just seems to jump off the wall at you. The difference (to me) between Picasso and lesser talents that throw paint at a canvas and call it art, is that Picasso really could draw a lamp when he wanted to.
