A heavy italic slab serif with a compact, energetic build and strongly anchored serifs. Strokes are broad and consistent, with moderate contrast and smooth, rounded joins that keep the texture dense but readable. Serifs are sturdy and mostly rectangular with subtle bracketing, while several letters show rounded or teardrop terminals (notably in lower-case forms) that soften the mass. Counters are generous for the weight, and the overall rhythm is forward-leaning with crisp diagonals and stable horizontals.
Best suited for headlines, decks, pull quotes, and poster typography where a strong italic voice is needed. The dense, slab-serif structure also works well for bold packaging statements, labels, and branding systems that want a vintage-meets-sporty edge. Use at medium to large sizes to let the heavy forms and terminals stay crisp.
The tone is assertive and high-impact, mixing a classic print feel with a brisk, athletic slant. It reads as bold and persuasive—more headline-driven than quiet—suggesting heritage, authority, and momentum at the same time.
The design appears intended to deliver an emphatic italic slab serif that holds together under heavy weight, combining sturdy serifs with rounded detailing to keep forms approachable. It aims for attention and authority in display settings while maintaining enough internal space for legible word shapes.
The lowercase includes single-storey shapes (such as the a) and a robust, slightly condensed feel in several forms, which amplifies word-shape contrast in italics. Numerals are weighty and stable, with rounded bowls and clear silhouette differentiation suited to large-size use.
