Like graphic design, fashion, and architecture, fonts are a part of the visual expression of an era and can experience popularity again, even decades later. The typefaces referred to as retro fonts have historical references and are, in their own way, very modern and trendy (again). This is true of the fonts from the art nouveau period as well as the structured grotesques of the Bauhaus era, the curvy advertising fonts from the 1950s, and the technical, rounded designs of the 1970s. Sometimes these fonts consciously pick up on their age and simulate a partial color application.
