A heavy, sturdy slab serif with thick rectangular stems and pronounced, squared serifs. The letterforms show noticeable contrast between main strokes and joins, with rounded/bracketed transitions that keep the shapes from feeling purely geometric. Curves are broad and full (notably in C, G, O, and S), while horizontals and terminals read crisp and flat, producing a dense, poster-ready texture. Lowercase forms are compact with strong, club-like terminals and a robust shoulder structure, and the numerals follow the same bold, high-impact construction.
Best suited to headlines, posters, packaging, and brand marks that need immediate impact and a sturdy, tactile presence. It also performs well for signage and short editorial callouts where a strong typographic voice is desired, rather than long-form text.
The overall tone is assertive and punchy, with a pragmatic, workhorse energy that leans industrial and slightly vintage. Its bold slabs and compact counters create a no-nonsense voice that feels confident, attention-grabbing, and built for display-led typography.
The design appears intended to deliver maximum visual weight and authority with a classic slab-serif structure, combining flat terminals with rounded joins for a friendly-but-tough display personality. It prioritizes bold legibility and a dense typographic color for branding and high-contrast layouts.
Spacing and silhouettes emphasize a solid, dark color on the page, especially in paragraph settings where the heavy serifs and compact apertures create a strong rhythm. The design maintains consistency across caps, lowercase, and figures, giving headings and short lines a cohesive, forceful presence.
