Context paragraphs:
FF Scala: FF Scala is an old-style serif typeface designed by Dutch typeface designer Martin Majoor in 1990 for the Muziekcentrum Vredenburg in Utrecht, the Netherlands.  The FF Scala font family was named for the Teatro alla Scala (1776–78) in Milan, Italy.  Like many contemporary Dutch serif faces, FF Scala is not an academic revival of a single historic typeface but shows influences of several historic models.  Similarities can be seen with William Addison Dwiggins' 1935 design for the typeface Electra in its clarity of form, and rhythmic, highly calligraphic italics.  Eric Gill's 1931 typeface Joanna (released by Monotype Corporation in 1937), with its old style armature but nearly square serifs, is also similar in its nearly mono-weighted stroke width.

Egyptienne (typeface): Égyptienne is a French serif typeface belonging to the classification slab serif, or "Egyptian," where the serifs are unbracketed and similar in weight to the horizontal strokes of the letters.  Egyptienne was designed in 1956 by Adrian Frutiger for the Fonderie Deberny et Peignot and was the first new text face created for the process of phototypesetting.

3x3: 3x3 is a typeface based entirely on a 3×3 bitmap matrix.  It was created by type designer Anders de Flon, who long refused to release the typeface before 2005, due to the large type foundries' demand for only complete ones (which means lower case characters, exclamation mark etc., i.e. 94 ASCII characters at least or in general).

Frutiger (typeface): Frutiger (pronounced with a hard g) is a series of typefaces named after its Swiss designer, Adrian Frutiger.  Frutiger is a humanist sans-serif typeface, intended to be clear and highly legible at a distance or at small text sizes.  A very popular design worldwide, type designer Steve Matteson described its structure as "the best choice for legibility in pretty much any situation" at small text sizes, while Erik Spiekermann named it as "the best general typeface ever".

Georg Trump: Georg Trump (1896–1985) was a German graphics, typeface and postage stamp designer, known for designs such as the book typeface Trump Mediaeval (1954), the slab serif City ( 1931) and the condensed, industrial Schadow.

Architype Albers: Architype Albers is a modular stencil sans-serif typeface based upon a series of experiments between 1926 and 1931 by Josef Albers, German designer, educator and typographer, (1888–1976).  The Architype Albers typeface is one of a collection of several revivals of early twentieth century typographic experimentation designed by Freda Sack and David Quay of The Foundry.

Zapfino: Zapfino is a calligraphic typeface designed for Linotype by typeface designer Hermann Zapf in 1998.  It is based on an alphabet Zapf originally penned in 1944.  As a font, it makes extensive use of ligatures and character variations (for example, the lower case letter d has nine variations).

Typeface: In typography, a typeface (also known as font family) is a set of one or more fonts each composed of glyphs that share common design features.  Each font of a typeface has a specific weight, style, condensation, width, slant, italicization, ornamentation, and designer or foundry (and formerly size, in metal fonts).  For example, "ITC Garamond Bold Condensed Italic" means the bold, condensed-width, italic version of ITC Garamond.  It is a different font from "ITC Garamond Condensed Italic" and "ITC Garamond Bold Condensed," but all are fonts within the same typeface, "ITC Garamond."  ITC Garamond is a different typeface from "Adobe Garamond" or "Monotype Garamond."  (These are all alternative updates or digitisations of the typeface Garamond, originally created in the 16th century.)

Lexicon (typeface): Lexicon is a serif typeface designed by Dutch type designer Bram de Does between the years 1989 and 1992.  The typeface was specially designed for use at very small point sizes in Van Dale's "Dictionary of the Dutch Language".

Adrian Frutiger: Adrian Frutiger (24 May 1928 – 10 September 2015) was a Swiss typeface designer who influenced the direction of type design in the second half of the 20th century and into the 21st.  His career spanned the hot metal, phototypesetting and digital typesetting eras.  Until his death, he lived in Bremgarten bei Bern .
