Irving Harper was a designer working alongside George Nelson in the 1960s. He designed the iconic Herman Miller logo, and even the Marshmallow sofa that was often attributed to George Nelson. But he didn’t get the recognition that many of his colleagues did. Now, a book called Irving Harper: Works in Paper, is out and stands as a beautiful tribute to this creative genius. Here are some of his personal paper projects, which look fantastically modern, 60 years on. Beautiful stuff.
