A sturdy slab-serif with pronounced, block-like serifs and clear bracketing into the stems. Strokes show noticeable contrast, with heavier verticals and slightly lighter connecting strokes, while curves stay smooth and controlled. Capitals are broad and steady with strong horizontals; the lowercase maintains a conventional, readable skeleton with a moderate x-height and generous internal space. Overall spacing and rhythm feel even and text-forward, with confident, squared-off terminals and solid punctuation and figures.
Well suited to editorial typography such as books, magazines, and long-form articles where a sturdy serif texture is desired. It also works effectively for headlines, subheads, and institutional or heritage-leaning branding that benefits from strong serifs and a confident presence.
The tone is traditional and dependable, with a bookish seriousness that reads as established and institutional. Its heavy slabs and firm proportions give it a grounded, no-nonsense voice, while the moderate contrast keeps it from feeling mechanical.
The design appears aimed at providing a reliable slab-serif voice that balances durability and readability. It emphasizes clear shapes, strong serifs, and controlled contrast to deliver a classic, editorial feel that can scale from text to prominent titles.
In text, the face holds a consistent color and stays legible at larger paragraph sizes, with slabs that remain visually present without overpowering counters. Numerals and capitals carry a slightly poster-like solidity, suggesting it can bridge between editorial text and display settings when set with comfortable leading.
