This illustration is of an Alfa Romeo GTA race car. At the time Alfa Romeo were very active in motorsport. The GTA model was built for racing with the A standing for Alleggerita (Italian for lightweight).
This particular car was built in 1965 and the picture was inspired by seeing it race at the Spa Classic in 2015. It was taking part in a race for touring cars with an engine capacity of less than two litres.
The image is available as a giclée print (see additional information). Each print is signed by the artist Steve Goodwin.
