Typefaces
- Lake Informal, designed for Linotype in 1935, though matrices were evidently never cut, as there is no record of this type having ever actually been cast in metal. Design later used for so-called "digital type" in 1993.
- Ruzicka Freehand, proposed designs made for Linotype in 1939 and never made into actual type. A digital knock-off of this design was made in 1993 by Ann Chaisson and Mark Altman.
- Fairfield series
- Fairfield + Italic (Mergenthaler Linotype Company, 1940). Perhaps twenty digital variants of this face have been designed by Alex Kaczun for Linotype.
- Fairfield Medium + Italic (Mergenthaler Linotype Company, 1949). A digital knock-off of this has been issued by Bitstream as Transitional 751.
- Primer + Italic (Mergenthaler Linotype Company, 1953), designed for legibility and to compete with A.T.F.'s Century Schoolbook. A digital knock-off of this has been issued by Bitstream as Century 751.
