OSP-DIN by Ludi Harrisson and Antoine Begon of OSP is a free condensed sans serif with a stark, engineered build and sharply changing stroke widths. Its towering letters are exceptionally narrow and firmly upright.
Industrial subjects suit it best, particularly transport posters, architecture branding, exhibition graphics, and technical event signage, where the compressed forms can echo machinery and structural frameworks. In editorial design, it can turn a magazine cover line or section opener into part of the publication's graphic architecture, with the lettering functioning almost like beams or columns.
