Appledesign: The Work of the Apple Industrial Design Group
Published in October 1997, Appledesign: The Work of the Apple Industrial Design Group is a 288-page book that looks at the design languages Apple used up until that time. With 400 color photos, this coffe-table book documents the industrial design that even then was ahead of its time — and remember, this is before things like the iMac and iPhone came along.
