One time during the early eighties when I met up with Milt Kahl in San Francisco, I asked him for a sketch of one of his characters. He felt a little uncomfortable with my request, on one hand he knew that I would very much appreciate it, on the other he thought that he wasn't up to his old drawing standards anymore.
Since I had brought a couple of stills showing Shere Khan  (I had made these prints from pieces of actual 35mm film), he looked at them and said:
"Yeah, these are good, these are good poses." 
Milt then went on to sign one image, as you can see below.
Just look at the stylized anatomy of the tiger, still takes my breath away.
