A sturdy slab serif with crisp, square-cut terminals and bracketless serifs that read as firm and architectural. Strokes show noticeable contrast (especially in rounds and diagonals), while the serifs remain blocky, producing a clear, rhythmic texture. Proportions are moderately narrow in many capitals with generous counters; lowercase forms are traditional and readable, with a two-storey “a” and a looped descender on “g.” Numerals are lining and sit confidently on the baseline with open, well-defined shapes.
Well-suited to editorial typography and long-form reading where a classic slab serif voice is desired, and it also holds up in display sizes for headlines. The firm, squared details make it a good fit for institutional branding, packaging, and signage that benefits from a stable, traditional presence.
The overall tone is traditional and authoritative, with a print-forward, literary feel. Its squared serifs add a pragmatic, no-nonsense edge that suggests reliability and formality rather than playfulness.
Likely intended as a dependable slab serif for print-centric settings, balancing classic letterforms with assertive square serifs to deliver a confident, legible tone across text and display use.
The design emphasizes clarity in mixed-case settings: prominent verticals and squared serifs create strong word shapes, while round letters maintain ample interior space. The “Q” has a distinctive tail treatment and the “R” leg is sharply defined, reinforcing a crisp, structured personality.
