neue Radial A follows the idea of New Functionalism that cultivates the model of the original London underground typeface in some details, while neue Radial B exemplifies the roots of a rational grotesque of the late twentieth century, a continuous success-story. neue Radial C is a contemporary representative of the geometric sans, mechanically constructed to optically appeal to the appearance of a true ‘compass and ruler’ typeface. Avant-Garde-esque elements ensure a smooth transition into neue Radial D that reflects the tradition of neo-grotesques.
