Martha Stewart Living, The Source, MensHealth, the Spanish edition of Playboy, Rolling Stone, The Montreal Gazette (Canada), and The Sunday Independent (London) have featured his faces. He has designed types for La Prensa Grafica (El Salvador) and El Universal (Mexico City). In 2002 he produced new headline series for The Wall Street Journal that satisfied complex contemporary requirements while remaining within the traditional typographic character that distinguishes the Journal.
The wide range of his work is important to Highsmith. He considers himself above all a draftsman. Drawing is his lifelong passion. He combines an energetic illustrative approach with enthusiasm for typographic communication, leading to a diverse library of original designs. Highsmith draws a calligraphic script for a wedding invitation as comfortably as an industrial strength sanserif.
