As a kid I was always searching for new Disney books which told stories using original stills from the movie. Looking at those film stills it felt like the movie stopped, and I had the chance to study the images thoroughly. Background paintings, inked or xeroxed cels and the overall color mood.
Then I discovered the Disney Golden Books. The pages in them showed special illustrations, in which the staging was often re-arranged to tell the story in a comprehensive way. Veteran studio background artists like Al Dempster, Gustaf Tenggren and even Mary Blair created beautiful paintings in Gauche or Watercolor.
Disney Editions recently published The Art of Disney Golden Books by Charles Solomon. It has great insight into the history of this popular book series. The art work is brilliantly reproduced, and each illustrator is profiled. I highly recommend this book:
