Peter started as a sketch in the static sans-serif tradition of Helvetica®. Then slight references to the calligraphic origin of type were added, giving it a more distinct character. This neo-grotesque sans has rational and clear basic letterforms, while in its details it unfolds attributes of humanist type. As a neo-grotesque sans it claims a very modest design, yet being a bit wider than its relatives and offering the warmth of humanist drafts. The early sketch grew to a type family of 18 fonts and now supports 700+ glyphs with pro opentype features.
