An original colour slide from the estate of renowned Ferrari historian Jess G. Pourret, accompanied by a modern photographic print produced from the original transparency. The image depicts Ferrari 250 GTO chassis 3909 GT competing at the Nürburgring in 1963. The original slide is annotated in Pourret's hand identifying the event and chassis, and credits the original photographer Bernard Cahier. The transparency formed part of the photographic archive assembled by Pourret and was retained for use in the preparation of his Ferrari publications - it features on page 129 of his seminal work Ferrari 250 GTO. 

An original working photograph from one of the foremost authorities on Ferrari history.
