Chuck Close turns 80. Good for him. I am not a fan. There are lots of artist that bore me more, yes. His painterly pixelations are pleasing and highly repetitive. It used to be a goal for people to sit for him.
In the beginning his way of showing people was interesting. He did not really develop from there. But that is sometimes exactly what you need to be successful as an artist: Not to confuse the market with different things you might care about. If Chuck ever did is not clear.
