Less than a month after Dieter Rams‘ eightieth birthday, Pentagram will hit the big 4-0. (Coincidence? You be the judge.) To celebrate four decades of eye-popping work, Naresh Ramchandani and Tom Edmonds in the London office whipped up “The Forty Story” (below). The film tells the story of a boy born on the day Pentagram opened—June 12, 1972—and how his life has been tracked (and kerned) by four decades of Pentagram design. Here’s to forty more years.
