The Kombine fonts are experiments in font mashups. My inspiration was found in Blackletter: Type and National Identity (Cooper Union, 1998, p.33). There was a small illustration of a font called "Centralschrift (C. G. Schoppe Foundry) 1853, a 19th c. hybrid of fraktur and a neo-classical roman". The upper parts--those which most enable reading--are the more familiar roman, producing a more legible font for those (like me) unfamiliar with the fraktur.
I used as my models a Wittenberger fraktur and various members of the Century family, recognized for its legibility. In working with the fraktur, I was reminded that its origin is in pen calligraphy. A natural extension then was the companion italic (Kombine Kursiv), an anomaly in blackletter type which has never used the upright roman/inclined italic convention.
