A heavy slab serif with broad proportions and strongly defined, squared-off serifs. Strokes show pronounced thick–thin contrast for the weight, with robust verticals and narrower joins that create crisp internal counters. Terminals are flat and confident, and several shapes show small notches and tight joins that read like ink-trap or cut-in detailing at stress points. The lowercase is compact with sturdy stems and short-to-moderate ascenders, while rounds (o, c, e) are full and slightly squared in feeling. Numerals are bold and stable, with a clearly open, modern 4 and rounded 6/9 forms that match the typeface’s dense color.
Best suited to display roles where impact matters: posters, headlines, storefront or wayfinding-style signage, and bold packaging. It can also support short editorial subheads or pull quotes when set with comfortable spacing, but it’s primarily a statement face.
The overall tone is forceful and attention-grabbing, with a classic, workmanlike slab-serif attitude. It suggests vintage editorial and signage traditions while staying clean and controlled, giving headlines a confident, slightly rugged authority.
The design appears intended to deliver maximum presence with a traditional slab-serif backbone, combining assertive block forms with refined contrast and crisp internal shaping to keep large text sharp and legible.
Spacing in the samples appears generous for the weight, helping keep counters readable despite the dense black mass. The uppercase has a strong poster rhythm, while the lowercase maintains a sturdy, utilitarian texture suitable for short bursts of text at larger sizes.
