Ambulatoria B

Ambulatoria is a sturdy open aperture sans-serif that comes in four variations. Each variation, A, B, C, and D, contains alternative variants for certain glyphs that allow the designer to change character and texture of the text.
 
The font family contains 80 fonts altogether, each sporting rich language support including pan-European Latin and Cyrillic. The typeface is intended to work in both large and small text sizes, which makes it a versatile workhorse.
