A heavy slab-serif with blocky proportions, gently bracketed serifs, and subtly softened corners that keep the forms from feeling rigid. Strokes are sturdy and fairly even, with small notches and flared joins that create a hand-inked, slightly uneven rhythm across lines. Uppercase forms are broad and stable; lowercase keeps a straightforward structure with rounded bowls and short, stout terminals that read clearly at display sizes. Numerals match the same chunky footprint and show the same slight irregularity in stroke endings and curves.
Best suited to display typography such as posters, headlines, labels, and storefront-style signage where the chunky slabs and lively terminals can carry personality. It can also work for short bursts of text (pull quotes, subheads) when a bold, vintage-leaning voice is desired.
The overall tone is bold and showy, with a frontier-style warmth and a lightly mischievous, handmade character. Its bouncy details and chunky slabs give it a nostalgic, sign-painting energy that feels friendly rather than formal.
The design appears intended to merge classic slab-serif sturdiness with a slightly irregular, hand-touched finish, creating a confident display face that feels at home in retro and western-inspired branding contexts.
Spacing and silhouettes lean toward headline impact, with distinctive serif shapes and small asymmetries that add texture in longer settings. The texture becomes more animated as size increases, where the bracketed slabs and quirky terminals are easiest to appreciate.
