When studying illustration at the Chelsea College of Art, Calvert encountered Jock Kinneir as a tutor and soon joined his office. In 1957, Calvert and Kinneir presented Transport sans serif font for road signs in the United Kingdom. Kinneir and Calvert’s designs changed the British landscape and became a role model for modern road signage all over the world. By the early 60s, Kinneir and Calvert were engaged to create an identity for the British Railway system. Their resulting typeface—Rail Alphabet—was meant to provide viewers on a platform with a clear, effective break from the busy advertisements that surrounded station signs.
