This font set is based on drawings by Frank Lloyd Wright for his exhibition lettering designed in 1931. His actual text stated: "A type face and alphabet of architectural lettering entitled Frank Lloyd Wright intended primarily for exhibition drawings. Each letter constructed mechanically using only 45. and 65. slant lines and two compass curves except the 'S'. The construction of the letters and more important, their juxtapositions and word spacing conrolled by a system of unit measure based on a subdivision of the letter height." Also included are 72 extras based on frank Lloyd Wright's Geometric Designs.
