Pagini desenate in 1975 de Carson Van Osten, un cunoscut artist de la Walt Disney.
Carson Van Osten:
"I wrote and drew those sketches around 1975 and I'm so tickled to know that people still find them helpful today. It started as a slide presentation for my boss to show at the Disney meeting in Frankfurt. It went over so well that he asked me to expand on it when he returned. They printed 2000 copies and mailed it to all the Disney offices."
