NK127, by V. Romanov with later additions by Nikola Kovanobic, is a free Cyrillic display font with a stark constructivist mood. The letters feel tall, heavy, and architectural, mixing broad rectangular forms with softened inner curves and sharp diagonal cuts that keep the rhythm active instead of static.
It fits poster typography, record sleeves, title cards, mastheads, and exhibition graphics where a few big letters can do the work. As a free font, NK127 is especially convincing for short headlines and monogram-like marks, because its blocky silhouettes and carved notches create a bold pattern even before you read the word.
