(Amazon has a ship date of June 1st in the U.S.; publisher Chronicle Books says it will be available after May 18.)
The Art of Cars 2 will be 160 pages long, with main text by Ben Queen and Karen Paik. Director John Lasseter will provide the foreword or preface.
Paik wrote The Art of Ratatouille and To Infinity and Beyond!: The Story of Pixar Animation Studios. Queen, on the other hand, I don't know much about, so I'm waiting to hear back from Pixar and Chronicle.
If previous 'Art of' books are any indication, the cover shown is only temporary and will be replaced closer to publication.
