Herman Miller has a long tradition of styling its physical spaces with bold ads and graphics, a process it calls “environmental enrichment." Fans of the brand often ask where they can find these works of art, which prompted the company to reprint select pieces from its archives. The Timeline Ad (1958) was designed by Irving Harper with George Nelson & Associates to outline a 13-year stretch of Herman Miller history via an assortment of modern design's most celebrated and storied pieces.
