A heavy, right-leaning slab serif with compact proportions and strongly bracketed, blocky serifs. Strokes are robust with a clear contrast between verticals and connecting curves, and many joins show soft rounding that keeps the weight from feeling brittle. Counters are relatively tight, terminals are largely flat and squared off, and the overall silhouette reads chunky yet controlled. The lowercase is compact with a single-storey “a,” a rounded two-storey feel in forms like “g,” and sturdy numerals that keep the same dense, poster-ready color.
Best suited to headlines and display work where its dense color and slabby structure can deliver impact—posters, packaging, branding marks, and cover typography in particular. It can work for short editorial blurbs or pull quotes, especially when set with a bit of extra tracking and line spacing to avoid a crowded feel.
The tone is assertive and upbeat, with a nostalgic, print-led character that recalls headline type from mid-century advertising and sports/editorial layouts. Its bold, slanted rhythm feels energetic and persuasive, making lines of text look lively and intentional rather than delicate or formal.
The design appears intended to provide a bold, readable italic slab for attention-grabbing typography, pairing strong, squared serifs with softened joins for a sturdy but inviting voice. It prioritizes punch and momentum while keeping letterforms conventional enough for straightforward, high-contrast messaging.
In text settings the strong slabbing and tight internal spaces create a dark, even texture, so it benefits from generous size and spacing to maintain clarity. The italic slant is consistent and helps maintain forward motion across long lines, while the weight and bracketing give it a friendly, approachable sturdiness.
