The image shown depicts the iPhone was in work back in 1983. Hartmut Esslinger was responsible for this design of iPhone. Don't forget that he was also responsible for the design of Apple II. He has also made the beautiful Sony-Wega Concept 51K.
In 1982 he entered into an exclusive $1,000,000 per year contract with Apple Computer to create a design strategy which transformed Apple from a “Silicon Valley Start-Up” into a global brand. Setting up shop in California for the first time, Esslinger and Frogdesign created the “Snow White design language” which was applied to all Apple product lines from 1984 to 1990, commencing with the Apple IIc and including the Macintosh computer.”
