OSCA was founded in 1947 by Bindo, Ernesto and Ettore Maserati after the Maserati brothers had left the company that carried their family name. The marque's badges commonly used the O.S.C.A. initials as the main identity, often paired with wording that referenced Fratelli Maserati and Bologna, reinforcing the founders' engineering lineage.
Historic OSCA emblems are most often associated with a compact oval or shield-like badge format, using strong lettering and Italian racing colors rather than a highly pictorial symbol. Because the company was small and competition-led, its identity remained closely tied to racing cars, workshop craftsmanship and the Maserati brothers' reputation.
