From Caldecott & Co.
...McCay and I serve the same master, our child selves. We both draw not on the literal memory of childhood but on the emotional memory of its stress and urgency. And neither of us forgot our childhood dreams.
A quote from McCay:
"The principle factor in my success has been an absolute desire to draw constantly. I never decided to be an artist. Simply, I couldn't stop myself from drawing. I drew for my own pleasure. I never wanted to know whether or not someone liked my drawings. I have never kept one of my drawings. I drew on walls, the school blackboard, odd bits of paper, the walls of barns. Today I'm still as fond of drawings as when I was a kid - and that was a long time ago - but, surprising as it may seem, I never thought about the money I would receive for my drawings. I simply drew them."
