A heavy slab-serif design with broad, squared serifs and largely flat terminals that give it a solid, block-built silhouette. Strokes are thick and steady with minimal contrast, and curves are rounded but kept taut, producing an overall squarish rhythm in letters like C, O, and S. Proportions feel compact and dense, with sturdy verticals and generous slab feet that create a strong baseline presence. Counters are relatively closed and the joins are robust, supporting consistent color in text while retaining clear letter identities.
Best suited for display sizes where its thick slabs and compact rhythm can project authority—headlines, poster typography, and editorial openers. It can also work well on packaging and signage where a durable, straightforward voice is desired, especially in short lines or blocks of emphasis.
The tone is assertive and workmanlike, with an industrial, press-like solidity that reads as dependable and no-nonsense. It also carries a classic Americana/editorial flavor—suited to statements that should feel bold, established, and a bit vintage without becoming ornamental.
The design appears intended to deliver maximum impact through mass and structure: bold slab serifs, flat-ended strokes, and compact proportions that hold together as a strong typographic block. It aims for clarity and presence over delicacy, giving text a sturdy, print-forward character.
The uppercase shows pronounced slab detailing and strong horizontals, while the lowercase maintains the same weighty construction, keeping texture uniform across mixed-case settings. Numerals match the letters’ sturdy build, making the set feel cohesive for headings and short bursts of information.
