A robust slab serif with pronounced, block-like serifs and mostly uniform stroke weight. The shapes are wide and open, with rounded curves paired against squared-off terminals, creating a strong, steady rhythm. Serifs read as substantial and slightly bracketed, and many joins have softened transitions rather than sharp corners. Counters are generous and apertures stay open, helping the forms remain clear even at heavier text sizes.
Well-suited to headlines, subheads, and short-to-medium passages where a strong typographic voice is desired. It can work effectively in posters, signage, and packaging that benefit from bold presence and clear letterforms, and it can also serve editorial layouts where a traditional slab serif texture is appropriate.
The overall tone feels dependable and emphatic, with an editorial seriousness that can also lean collegiate or institutional. Its heavy slabs and broad proportions convey authority and stability, while the rounded curves keep it from feeling overly rigid or mechanical.
The design appears intended to deliver a classic slab-serif authority with contemporary clarity: big, confident letterforms, strong serifs for impact, and open counters for legibility. It prioritizes a bold, reliable texture that reads well in display settings while remaining composed in paragraph-like samples.
Uppercase forms appear especially commanding due to their breadth and strong serif footprint, while lowercase retains clear, workmanlike construction. Numerals match the same sturdy, slabbed voice and feel designed to sit comfortably alongside text rather than as decorative figures.
