Ostrich Proper is the completely redrawn, professional form of Ostrich Sans. It is better in every way, including lowercase characters and diacritics across all six weights. It’s long, winding curves and slightly condensed width give it an unmistakable personality. While the lighter weights are best used for large, display purposes, the heavier weights are built for any size.
