Olivia: the rounded Serif with edges
With or without: Olivia got both. Serif or Sans? Curves or edges?
Olivia got curves on the outlines and edges on the inlines. So it can be very legible and space efficient at the same time: the curves keep the distinctions between the letters, the corners keep the influences from broadnibbed pens with a subtle horizontal stress.
Olivia has personality without being obtrusive. With or without curves or edges.
Three weights (light, regular, bold), all with real italics, SmallCaps, different sets of figures, accents, arrows, symbols. And a fourth weight (black) without italics or SmallCaps. Olivia: with or without.
