"Wherever
he went, he always carried a sketchbook. And unobtrusively he
would slip it out of his jacket pocket and open it, concentrating
on his subject, in a way which didn't alert anyone nearby to
what he was doing. Even on a moving subway train or a bus he
would slip out his sketchbook, and holding his pencil or pen
in the proper manner, so that its length extended down from
the tips of his fingers to the point, he would make his annotation,
so that later on when you looked at it you would never be able
to tell that it had been executed on a moving subway train or
bus. He always had his sketchbook in readiness, slipped into
the pocket of his jacket, and whenever we went out together
we would sometimes have to stop as he made a hasty apunto, sketch,
perhaps of the head of a young woman, catching the emotion in
her expression, and then sometime later she might appear again
in one of his paintings, his sketch used as the model."
