A sturdy slab-serif with heavy, square-shouldered forms and short, emphatic serifs. Strokes are largely even in weight, with subtle flare and bracketing where stems meet serifs, producing a carved, print-like texture. Counters are relatively tight and the overall proportions feel compact and efficient, while spacing stays even enough to keep words coherent at display sizes. Numerals and capitals read particularly solid, with a no-nonsense, blocky silhouette.
Best suited to headlines, posters, and branding moments that need bold, high-impact typography with a vintage or institutional flavor. It also works well for short blocks of copy on packaging or signage where a strong, sturdy texture is desirable.
The font conveys a confident, workmanlike tone with a distinctly retro, poster-ready presence. Its dense rhythm and chunky details suggest traditional print and signage, leaning into a collegiate or heritage feel rather than a polished contemporary one.
The design appears intended to deliver a robust slab-serif voice optimized for display use: strong silhouettes, firm serifs, and compact proportions that hold up in large, attention-grabbing settings while maintaining a classic print sensibility.
The strong serifs and restrained apertures create a dark, continuous color in text, which increases impact but can reduce delicacy at smaller sizes. Curved letters retain a slightly squared-off tension that reinforces the overall sturdy character.
