John Lasseter mentions in the introduction his first job in college was pulling animation sequences from "the morgue" – Disney's archive of animation artworks. Well, this book is filled with those animation boards from "the morgue". Specifically, these are boards before the clean up process — before sketchy pencil lines are removed and colours, backgrounds added.
The second book in The Archive Series is still a huge thick hardcover with the boards printed gloriously big. Compared to the first volume, every artist is now properly credited to their work. There are a couple of fold-outs which I think are great because they allow more frames per page, and thus being able to appreciate the sequence in question easier, noticing the subtleties better without having to constantly flip pages back and forth.
This book is primarily on the character art and animation.
For animation sequences the boards included are actually a mixture of in-sequence and standalone. You'll probably be able to recognise the many memorable scenes, like how Dumbo swings from her mother's trunk , when Pinnochio takes his first step or the spaghetti-eating-to-kissing scene in The Lady and the Tramp.
Plenty of legendary artists are included, like Ub Iwerks, Norm Ferguson, Ben Sharpsteen, Hamilton Luske, Dick Huemer, Grim Natwick, Art Babbitt, Fred Moore, Bill Tytla, Frank Thomas, Ollie Johnston, Milt Kahl, Marc Davis, John Lounsbery, Ward Kimball, Eric Larson, Les Clark, Wolfgang Reitherman, John Sibley, Bill Justice, Clyde Geronimi, Ted Berman, Glen Keane, Andreas Deja, Eric Goldberg, Mark Henn and Tony Bancroft.
What I think is a drawback in this book is that, even though the book is quite thick and has quite a lot of boards, there are some key scenes missing. The lack of art from Robin Hood (there's just none), The Little Mermaid (really small selection) or Milt Kahls' astounding Shere Kahn (which the book contains only one frame).
Overall this book is great! It is worth every penny. I would recommend it to animators or great lovers of this kind of art because this book contains the raw snapshots from this hugely talented people and not perfectly finished pictures of how you it appears in the movies.
