At first glance, Typewriter Sans JNL seems to look like the pantograph lettering of an engraved sign or the rounded-end lettering from an architect’s templates. It might also be mistaken for plastic pin-back lettering used on some bulletin boards.

In actuality, the design is based on examples of an electric typewriter ball element with a sans font named “Dual Gothic”, suggested for use “in credit reports and other financial applications”.
