A heavy italic serif with broad, slab-like feet and subtly bracketed joins that soften the blocky structure. Strokes are sturdy and fairly even, with gentle modulation and rounded internal corners that keep counters open. The italic slant is pronounced, and the letterforms feel compact and weighty, with short, squared-off terminals and a slightly carved, ink-trap-like crispness at some joins. Uppercase forms are wide and stable; lowercase shows strong, upright stems with energetic diagonals and a robust, single-storey style where applicable.
Best suited to display work such as headlines, posters, book or magazine titling, and brand marks that need a confident, vintage-leaning voice. It can also work for short editorial subheads and packaging callouts where a dense, impactful italic is helpful, though the weight and slant make it less ideal for long-form body text at smaller sizes.
The overall tone reads classic and assertive, with a vintage print and sports-editorial flavor. Its slanted, chunky build gives it momentum and a slightly rugged, handmade warmth while remaining clear and authoritative.
The design appears intended to blend sturdy slab presence with an energetic italic stance, delivering strong readability and a memorable, retro-inflected silhouette for attention-grabbing typography.
Numerals are bold and sturdy with simple, highly legible shapes suited to large settings. The design maintains consistent mass across the set, producing an even, punchy texture in lines of text despite the strong slant.
