A condensed slab serif with tall proportions, sturdy vertical strokes, and crisp, square-cut terminals. The serifs read as rectangular blocks with minimal bracketing, giving the outlines a machined, stamped feel. Curves are tightened into narrow bowls and rounded corners are kept controlled, creating a consistent, upright rhythm and compact counters. The lowercase maintains a straight-sided, architectural structure, while the numerals follow the same condensed, vertical emphasis with firm, flat feet and caps.
Best suited to display work where a compact, high-impact voice is needed—headlines, posters, mastheads, and branding that benefits from a rugged, utilitarian presence. It can also work on packaging and signage where narrow letterforms help fit longer words into limited space.
The overall tone feels industrial and assertive, with a vintage poster and Old West–adjacent flavor. Its narrow, forceful shapes project authority and practicality rather than delicacy, suggesting signage, labels, and strong headlines.
The font appears designed to deliver maximum visual weight in a narrow footprint, pairing slabbed, square terminals with a disciplined, vertical structure. The intention seems to be a bold, vintage-industrial display style that remains orderly and consistent across letters and numerals.
The design relies on strong verticality and uniform, squared detailing, which helps it hold together in dense settings. The condensed width and tight apertures make it most legible when given enough size and spacing to breathe.
