A heavy, right-leaning slab-serif with compact, squared-off details and stout, blocky proportions. Strokes are consistently thick with moderate modulation, and the counters stay relatively open for the weight. Serifs read as bold slabs with crisp, flat ends and subtle shaping at joins, producing a carved, poster-like silhouette. The lowercase shows a tall, prominent x-height and sturdy stems, while figures and capitals maintain a dense, impactful rhythm with slightly lively, varied widths.
Best suited to display roles where weight and character are assets: posters, headlines, product packaging, badges, and bold branding systems. It can also work for short subheads or callouts where a compact, punchy italic slab adds emphasis, but it will feel most at home at larger sizes.
The overall tone is bold and energetic, mixing vintage sign-painting flavor with a confident, athletic punch. Its chunky slabs and italic slant add motion and a bit of swagger, giving headlines a spirited, attention-grabbing character.
This font appears designed to deliver maximum impact with a vintage-leaning, sign-inspired voice—combining chunky slab serifs, a forward slant, and tall lowercase proportions to stay readable while looking bold and distinctive.
The design’s square terminals and thick slabs create strong horizontal emphasis, which helps it hold together in short bursts of text while remaining highly graphic. The italic angle is evident without becoming cursive, keeping the letterforms sturdy and billboard-ready.
