- Looking back as far as man"s first efforts to communicate with visual signs and drawings, Letter Fountain is a completely unique typeface handbook: in addition to examining the form and anatomy of every letter in the alphabet (as well as punctuation marks and special characters), the book cross-references type designs with important works of art and art movements from Gutenberg"s times until today. Further attention is given to the esthetics of the digital age and typographical recommendations such as the choice of the right typeface for a job. Rounding out the guide are an in-depth comparison between sans-serif and serif typefaces, an essay about measuring systems and indications, advice about typographic rules, plus a manual for developing digital fonts.
