I’ve long wanted to link to Irving Penn but whenever I was looking for links it turned out to be very slim pickings. In that sense, the internet can be quite deceiving: If you try to estimate popularity or importance by the number of links you can find you might be making quite a serious mistake. In any case, I fould a few more links with a small number of samples: Two brief bios/introductions, here and here; and three samples plus text for his “Nudes”.
