A heavy, block-built slab serif with broad proportions and compact counters. Strokes are thick and relatively even, with square-cut slab terminals and small carved notches at joins and corners that read like subtle ink traps. Curves are full and rounded while interior spaces stay tight, producing a dense texture. Lowercase forms are large and sturdy with simple, single-storey shapes, and figures are similarly weighty and wide-shouldered for strong, graphic impact.
Best suited to big, attention-grabbing settings such as posters, mastheads, event graphics, storefront signage, and bold packaging. It can also work for short pull quotes or title cards where a compact, high-impact texture is desirable.
The overall tone is loud, confident, and showmanlike, with a vintage poster feel. Its chunky silhouettes and cut-in details add a playful, slightly rugged flavor that suggests headlines, signage, and display typography rather than quiet text setting.
The design appears intended to deliver maximum visual weight and immediacy with a retro slab-serif voice. The carved corner detailing suggests an effort to keep shapes crisp and distinctive in large display use while maintaining a friendly, rounded overall silhouette.
The distinctive corner notches and squared slabs create a crisp, stamped look even though many curves are generously rounded. The dense spacing and compact apertures can cause words to visually “plug up” at smaller sizes, but they amplify presence at display scales.
