From the publisher:

The Pixar Treasures is a scrapbook of instinct and inspiration, experiences readers can touch, and visions that exist only in the imagination. It begins with a group of animators who were inspired by Walt Disney films. In the late 1970s and early '80s, John Lasseter, Brad Bird, and Joe Ranft were hired into an apprenticeship program at Walt Disney Productions. The last of Disney's golden age artists, including animators Eric Larson, Milt Kahl, Frank Thomas, and Ollie Johnston mentored the young dreamers, and as Pixar later developed, their work would draw heavily from this direct connection with Walt Disney's "Nine Old Men." The tale continues with Pixar's foray into computer animation, and the resulting success of Toy Story. With chapters on A Bug's Life; Monsters, Inc.; Finding Nemo; The Incredibles; Cars; Ratatouille; and WALL*E, Hauser's narrative covers the struggles, growth, and successes of an incredible animation studio (up to the Pixar film, Up). Filled with unique removable keepsakes, The Pixar Treasures is an essential collector's item for every Pixar fan.

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.
