From the publisher:

This book retells the classic story of Snow White and the Seven Dwarfs and the equally compelling history of its making. It reunites a trove of its rare, surviving original conceptual and production art from the incomparable private collection of Stephen H. Ison. From the opening approach to the evil Queen's castle to the final awakening of Snow White with a kiss from her true love, each illustrated drawing freezes in time an image that had its momentary but indelible existence on the screen.

This came from the library of Burny Mattinson (1935-2023), an animator, director, producer, and story artist for Walt Disney Animation Studios, from 1953 until his death in 2023. Mattinson directed Mickey's Christmas Carol and The Great Mouse Detective. He was named a Disney Legend in 2008 and was the longest serving employee of The Walt Disney Company, with a career that spanned almost 70 years. His extensive library included numerous subjects and especially large collections of books on Disney, animation, and classic comic strips.
