Aeronaut is an homage to the Neogothic of the late 1800s, a style that combined mediaeval gothic elements with Arts & Crafts influences. The font was inspired by a liturgical alphabet called Kirchengotische Schrift that was found in a 1879 German sample book for lettering artists. Like FaceType’s recent Ivory, it has been designed for bi-color compositions. While the regular Aeronaut comes as an alphabet of ornamental letters, the letters in the Aeronaut Base font are ‘undressed’, so to speak. Ornaments can be added from one of the specially priced ornament fonts: Parachute and Balloon (the latter has longer hairlines). Letters and ornaments have corresponding widths, so they can easily be layered in contrasting colors.
