Acier, as an “Antique”, is a self-assumed modernist typeface and mixes several influences: above all, functionalist decorative arts, design, and architecture, along with urban epigraphy. It is also emblematic of the various aspects of 19th-century display typography, exploring the fantastical and three-dimenional aspects that were fashionable at that time. Acier bears this link into the metal from which it took its name (NB: “Acier” means “Steel” in French), just as Jérôme Peignot notices: “Few typographic works have been so effective in connecting the physical and graphical worlds”.
