Letourneur & Marchand, located in the prosperous Paris suburb Neuilly-sur-Seine, was a car body manufacturing business which became one of the last French coachbuilders.

Unic was a French manufacturer founded in 1905, and active as an automobile producer until July 1938. After this the company continued to produce commercial vehicles, retaining its independence for a further fourteen years before being purchased in 1952 by Henri Pigozzi, who was keen to develop Unic as a commercial vehicle arm of the then flourishing Simca business.
