A heavy slab-serif with firm, squared-off serifs and a compact, authoritative color on the page. Strokes show noticeable contrast—thicker verticals paired with slightly finer joins and curves—while maintaining an overall robust presence. Counters are moderate and well-contained, curves are smooth but tightly drawn, and terminals end cleanly with flat, rectangular finishes. Proportions feel traditional and steady, with wide caps and sturdy lowercase forms that stay legible even at larger text settings.

Well-suited to headlines, subheads, posters, and identity work where a strong, traditional voice is needed. It can also work for editorial display applications and short text blocks that benefit from dense, high-impact texture and sturdy letterforms.

The font conveys a classic, dependable tone with a hint of collegiate and editorial gravitas. Its bold slabs and controlled detailing feel confident and slightly old-school, making it read as trustworthy and emphatic rather than delicate or playful.

The design appears intended to deliver a forceful slab-serif voice with classic proportions and crisp, squared finishing. Its emphasis on solid stems, substantial serifs, and controlled contrast suggests a focus on clarity and authority for display and branding contexts.

The numerals and capitals appear particularly strong and signage-friendly, with clear silhouettes and minimal ambiguity. The rhythm in continuous text is dense and even, creating strong emphasis and presence in headlines and short blocks.
