A heavy slab-serif with broad, squared-off serifs and largely unbracketed joins that give the letterforms a blocky, engineered feel. Strokes are robust and fairly consistent in weight, with compact counters and clear, straight-sided stems that emphasize verticality. The lowercase is solid and workmanlike, with a single-storey ‘a’ and ‘g’ and a strong, squared shoulder structure; curves are rounded but controlled, often finishing into flat terminals. Numerals are bold and wide-set, with simple, legible shapes and a noticeable, poster-like presence.
Best suited to headlines, titles, and short blocks of text where strong typographic color is desired—such as posters, editorial display, packaging, and brand marks. It can also work for signage and callouts where robust shapes and clear character differentiation are needed.
The overall tone is sturdy and assertive, with a pragmatic, no-nonsense voice that reads as both vintage-inspired and industrial. Its dense color and squared detailing convey confidence and emphasis, making text feel declarative and headline-driven.
The design appears intended to deliver maximum impact with a sturdy slab-serif structure and square terminals, balancing traditional serif cues with a more industrial, contemporary solidity for attention-grabbing display typography.
The uppercase has a formal, sign-like rhythm with prominent slabs that hold lines together, while the lowercase keeps a friendly readability through open apertures and straightforward construction. The heavy serifs and compact internal space increase visual density, so it naturally draws attention at display sizes.
