He created a Univers font variation — a set of capitals and numbers specifically for white-on-dark-blue backgrounds in poor light. He also designed a slab serif font for the . Frutiger's 1984 typeface Versailles is an old-style serif text with capitals like those in the earlier . Versailles is a Latin design with sharp wedge serifs, based on a popular genre in 19th-century printing. Avenir In 1988, Frutiger completed the family . Frutiger intended the design to be a more human version of geometric sans-serif types popular in the 1930s such as Erbar and Futura, and it is named ("future" in French) as a reference to the latter. In a complete reverse, his next design Westside was a wild-west themed slab serif, inspired by reverse-contrast French Clarendons of the late 19th century. Late designs In 1991, Frutiger finished Vectora, a design influenced by Morris Fuller Benton's type faces Franklin Gothic and News Gothic.
