A heavy slab-serif with compact proportions, broad verticals, and consistently low-contrast strokes. Serifs read as thick, squared slabs with subtle bracketing, giving corners a slightly softened, carved look rather than razor-sharp geometry. Counters are relatively tight and apertures tend to be closed, creating dense color and strong presence in text. Curves are robust and rounded into the stems, and several joins suggest an ink-trap-like widening that helps preserve interior space at heavy weight.
Best suited to headlines, posters, and branding where strong typographic color and immediate impact are needed. It can also work for packaging and signage that benefits from sturdy, traditional slab-serif cues, especially at medium-to-large sizes where counters remain clear.
The tone is confident and workmanlike, with a vintage, print-forward character that recalls utilitarian signage and bold editorial headlines. Its dense rhythm and emphatic serifs convey authority and a slightly rugged, no-nonsense energy.
The design appears intended to deliver maximum impact and legibility in bold settings by combining thick, square-shouldered slabs with sturdy, low-contrast construction. Subtle bracketing and reinforced joins suggest an aim for a durable, print-friendly look that stays cohesive across letters and numerals.
In continuous text the font produces a dark, even texture with short-looking ascenders and descenders and pronounced vertical emphasis. Numerals are weighty and stable, matching the letterforms closely for display-oriented compositions.
