Neutraface
Neutraface is a geometric sans-serif typeface designed by Christian Schwartz for House Industries, an American type foundry. It was influenced by Richard Neutra's design principles and was developed with the assistance of Neutra's son and former partner, Dion Neutra.
The general purpose versions of Neutraface are Neutraface Display and Neutraface Text, and since its initial release the Neutraface family has expanded with the variants Neutraface Condensed, Neutraface Slab and Neutraface No. 2.
