An outlined serif design built from hairline contours with a consistent inner counterline, creating an inline/engraved effect rather than a filled stroke. Proportions are classical and balanced, with moderate caps and a regular, readable lowercase. Serifs are bracketed and neatly finished, and curves are smooth and slightly calligraphic in places (notably in C, G, S, and the lowercase a). The overall rhythm is even, with clear counters and careful spacing that keeps the thin outline from feeling brittle.
Best suited to headlines, short phrases, and identity work where the outlined detail can be appreciated—such as packaging, invitations, editorial display, and signage. It can work for longer passages at larger point sizes, but the hairline outlines suggest avoiding very small sizes or low-contrast reproduction.
The tone reads refined and old-fashioned, like letterpress titling or engraved stationery. Its hollow construction gives it an airy, polished presence that feels formal without becoming heavy, lending a subtly ornamental, archival character.
The design appears intended to provide a classic serif voice with a decorative, engraved outline treatment—bringing traditional book typography proportions into a lighter, more ornamental display style.
The outline construction is most convincing at display sizes, where the double-line structure stays crisp and the internal spacing doesn’t close up. Numerals follow the same elegant, lightly embellished logic, with gently curved terminals that match the serifed text forms.
