Hi Fumiko,
I hope you are doing lovely
I was at a signing in Sidney, Australia. Tony was there most of the day doing sketches and drawings. In between my signing for people, he asked me to do some quick drawings on his papers. And then he would continue to add to it or paint over it.
It was a fun idea.

And he showed me his autobiographical sketchbooks and comics there as well.
