Exported to Egypt early in its life, it was then sold on to a Swiss owner who used it to compete in the Les Rangiers Hillclimb.
It moved between America and Switzerland over the following decades and was awarded Best in Show at the 1996 Concorso d’Eleganza Villa d’Este after being restored.
Further accolades followed, including First in Class at the 2000 Pebble Beach Concours d’Elegance.
Following its high-profile theft and recovery, the Alfa Romeo now returns to Pebble Beach, where it headlines the Gooding & Co sale.
Also among the lots is the Porsche 935 Chassis 001 — the factory prototype that forged the path for the phenomenally successful 935 line, which went on to win at Le Mans, Sebring and Daytona.
The car, which also claimed a victory of its own at the 1976 6 Hours of Watkins Glen, is being sold in Martini livery with a $4.5m to $5.5m (£3.5m to £4.3m) estimate.

A Ferrari 250 GT Berlinetta Competizione once owned by Alfonso de Portago, who sold it a year before his tragic 1957 Mille Miglia crash, also carries a $4.5m to $5.5m estimate,
Less expensive, but with impeccable Formula 1 heritage is 1960 Lotus Type 18, which finished third at the 1960 Portuguese Grand Prix in the hands of Jim Clark, and was also raced by Graham Hill, John Surtees and Innes Ireland. It is estimated to sell for between $400,000 and $600,000.
