Direction of Travel is a project by Christian Nolle, a half Danish/half German London based artist and map collector. He has spent decades creating work, often in photographic form, that looks at the interplay between aviation, politics and the cities we live in. Christian is also the Founder and Head of Good Caesar, a design and technology studio.

"Rudy is one of the unsung pioneers of American mid-century modernist graphic design. He had a unique and definitive point of view that was really never celebrated. This may have been attributed to his strict adherence to the formal principles of modernism and the International Typographic Style."
