Folio由Konrad F. Bauer和Walter Baum共同设计，并于1956年至1963年间由Bauer Type Foundry以多种字重和宽度发布。这款清晰的无衬线家族与Helvetica大约在同一时间设计，在许多方面与Helvetica非常相似。某些字符会有一些明显的不同，例如小写字母a，以及大写字母G和Q。Folio的设计师团队合作开发了其他几种Bauer字体，包括Volta和Impressum。Konrad Bauer还是著名的字体排印教师与历史学家。他在1940年写了《 Aventur und Kunst》一书。当您需要传达技能和清晰度，并且想要一些与Helvetica不太一样的东西时，请使用Folio。

Folio was designed by Konrad F. Bauer and Walter Baum, and released in several weights and widths by the Bauer Type Foundry from 1956 to 1963. This legible sans serif family was designed around the same time as Helvetica, and in many ways it is quite similar to Helvetica. There are some notable differences in certain characters, like the lowercase a, and the caps G and Q. The designers of Folio worked as a team on several other Bauer types, including Volta and Impressum. Konrad Bauer was also a notable typography teacher and historian; he wrote the book "Aventur und Kunst" in 1940. Use Folio when you need to communicate competence and clearness, and when you want something just a little bit different from Helvetica."
