A heavy oblique slab-serif with thick, even stroke weight and squared-off serifs that read as solid blocks. The letterforms show broad, sturdy proportions with compact counters and minimal taper, producing a dense, punchy color on the line. Curves are firm and rounded but controlled, while terminals stay blunt and flat, reinforcing a strong, mechanical rhythm. Uppercase forms feel particularly weighty and stable; lowercase is similarly robust with a straightforward, no-nonsense structure.
Best suited to display settings where strong typographic impact is needed—posters, headlines, and promotional graphics. It can also work well for sports-related branding, labels, and packaging where a tough, vintage-leaning voice is desirable. In editorial design, it fits pull quotes, section openers, and bold titling where the dense texture can be a feature.
The overall tone is bold and direct, with a distinctly vintage, poster-like confidence. Its slanted stance adds motion and urgency, giving it a sporty, attention-grabbing presence without becoming flashy. The chunky slabs and tight apertures lend a rugged, workmanlike character suited to loud messaging.
The design appears intended to deliver maximum punch and legibility at larger sizes through thick slabs, blunt terminals, and a forceful oblique stance. It prioritizes strong silhouettes and a consistent, heavy rhythm for branding and headline use, evoking traditional poster and athletic typography cues.
The numerals are large and blocky with clear, simplified shapes that match the uppercase’s weight and stance. Spacing and sidebearings appear tuned for impactful set text, creating a strong continuous texture in words and short lines. The heavy serifs and compact internal spaces suggest best performance at display sizes rather than small text.
