LFT Arnoldo began as an all-caps book cover typeface for the rebranding of Oscar Mondadori, an Italian publisher with over 4,500 titles spanning highly varied genres and readerships. The design required a single coherent typeface to serve as a unifying branding element across the entire catalogue. LeftLoft (Milan) built the initial capitals around a rational, contemporary structure with incised, stone-cut detailing, then extended the design into a full flared humanist sans family covering text and display use.
