Messenger is a redux of two mid-1970s Markus Low designs: Markus Roman, an upright calligraphic face, and Ingrid, a popular typositor-era script. Through the original film faces were a couple of years apart and carried different names, they essentially had the same kind of Roman/Italic relationship two members of the same typeface family would have. The forms of both faces were reworked and updated to fit in the Ingrid mold, which is the truer-to-calligraphy one.
The Messenger package is comprised of two interchangeable fonts that support Western, Eastern and Central European languages, as well as Baltic, Celtic/Welsh and Esperanto. Messenger Pro is a single OpenType font that contains the characters of both Messenger and Messenger Alt, linked by programmed features for stylistic alternates, automatic f-ligatures and class-based kerning.
