A heavy, square-shouldered slab serif with flat, rectangular serifs and crisp, straight terminals. Strokes are consistently thick with minimal modulation, producing a strong, even color on the page. Counters are relatively tight and geometry leans toward squarish bowls and firm verticals, while joins stay clean and uncluttered. The lowercase shows a single-storey a and g with compact apertures, and the figures are chunky with broad bases and strong horizontals.
Best suited to headlines, posters, and display copy where its dense weight and square slabs can deliver strong impact. It also fits branding, packaging, and signage that need a rugged, traditional voice and high visual presence. For longer text, it will work most comfortably at moderate sizes with generous spacing.
The overall tone is confident and workmanlike, with a poster-forward, no-nonsense presence. Its chunky slabs and tight internal spaces evoke vintage print, collegiate signage, and industrial labeling, reading as direct and sturdy rather than delicate or refined.
The letterforms appear intended to deliver a robust slab-serif voice with solid, rectangular finishing and a compact, high-ink texture. The design prioritizes impact and stability, aiming for a classic display feel that remains legible and consistent across uppercase, lowercase, and numerals.
At larger sizes the flat slabs and right-angled corners give a distinctly mechanical rhythm; at smaller sizes the dense counters may increase darkness and reduce openness in letters like e, a, s, and 8. The design maintains consistent weight across caps, lowercase, and numerals, helping it hold together in impactful headlines and short blocks of text.
