Irving Harper was known for his work on iconic 20th century designs with George Nelson, with the marshmallow sofa, ball clock, and even the Herman Miller logo. Since working with Nelson, he has been quietly building an incredible collection of paper sculptures, which surround him in his home. He champions the versatility and simplicity of the material, cutting, forming, bending and gluing it to make masterful modern animals, heads, and abstract geometric creations. Irving Harper: Works in Paper, out in February from Rizzoli, celebrates and reveals Harper’s hidden craft. For more on his paper work, check out this video.
