Keratine Font Family
The letterforms that we now accept as the historical standard for printing latin alphabets were developed in Italy around the end of 1400. Deriving from Roman capitals and from italic handwriting, they soon replaced the blackletter letterforms that were used a few years before by Gutenberg for his first moveable types. Between these two typographical traditions there's an interesting and obscure middleground of historical oddballs, like the Pannartz-Sweynheym Subiaco types, cut in Italy in 1462.
