From Apple’s news release:

Apple today announced the release of a new hardbound book chronicling 20 years of Apple’s design, expressed through 450 photographs of past and current Apple products. “Designed by Apple in California,” which covers products from 1998’s iMac to 2015’s Apple Pencil, also documents the materials and techniques used by Apple’s design team over two decades of innovation.

The book is dedicated to the memory of Steve Jobs.

And:

“The idea of genuinely trying to make something great for humanity was Steve’s motivation from the beginning, and it remains both our ideal and our goal as Apple looks to the future,” said Jony Ive, Apple’s chief design officer. “This archive is intended to be a gentle gathering of many of the products the team has designed over the years. We hope it brings some understanding to how and why they exist, while serving as a resource for students of all design disciplines.”

The book is available in two sizes:

• Small (10.20” x 12.75”)
 US$199
• Large (13” x 16.25”)
 US$299

Twenty years takes us back to 1996, the year CEO Gil Amelio made one of the most important decisions of his tenure, starting the process of bringing Steve Jobs back to Apple. The NeXT deal was finalized on February 9, 1997.
