Massimo Vignelli was one of the 20th century’s most prominent designers, creating everything from New York’s subway map to logos for American Airlines, Bloomingdale’s, and IBM. He died in 2014 at 83. His wife and creative partner, Lella, followed in 2016.

But just a year before Massimo’s death, documentarian Gary Hustwit–known for his “design trilogy” of films Helvetica, Objectified, and Urbanized along with a new profile of Dieter Rams–visited Massimo for an intimate photo shoot in his home. The photos will be published this September in an 80-page book you can pre-order today for $35. A portion of the proceeds will be donated to the Vignelli Center at Rochester Institute of Technology, which houses the complete archive of the Vignellis’ work.

Hustwit had known Massimo for nearly a decade by the time these photos were taken. Massimo was, in fact, Hustwit’s very first subject he interviewed for Helvetica back in 2005, and the two bumped into each other at design events frequently. “In 2013, I was getting more interested in still photography, and frankly I just wanted willing subjects I could photograph in order to get better at it. I thought about interesting people I knew in New York who might let me spend the day with them and be photographed, so I emailed Massimo and he graciously agreed,” recounts Hustwit. “I just wanted to try to capture what it felt being in that space with him and Lella at that point in their lives. He was in good spirits and seemingly good health that day. There was nothing to indicate to me that he’d be gone a year later.”
