No. 3 Series is a typeface for a variety of large scale applications including titling, visual identities, books, magazines, mobile patterns and websites. It has the characteristics of humanist letters and covers three widths in large steps, Normal, Narrow and Poster. Furthermore No. 3 Series is to a large extend influenced by writing and cursive writing, which inspired some of the first letters that were cut in metal during the Renaissance.
There are several details that refer to writing or italic writing. For example the principle behind the shapes of the a, d, p and q of the lowercase alphabet is the rotation of an italic letter written with a broad nib pen. Italic handwriting usually has a slope which in this case is reduced to zero, but the underlying theoretical strokes are preserved.
