Dutch (Old Style)

The faces were created mainly in Netherlands in the the 17th century based on the Garaldes lettershapes. Early in the 17th century the Elzevir family at Leyden and Amsterdam became major international publishers. Their best types, designed by Christopher van Dyck, are a refinement of Garamond. Later or Baroque old style type generally has more contrast, with a somewhat variable axis, and more slope of italic. Also it has narrow proportion and large x-height.
