The one-off Maserati 450S Le Mans Costin Coupé is to take centre stage at the Amelia Island Concours d'Elegance in March.
The rarely seen car with a fascinating history will be part of the Florida event's huge celebration of the Trident marque's centenary.
Created for Stirling Moss to drive in the 1957 Le Mans 24 Hours, it failed miserably due to lack of preparation time and the car being unfinished.
The following year American Byron Staver persuaded Maserati to convert Il Monstro into a road car, which involved stretching the wheelbase by 10in.
From 1978-2002 the car was displayed in the Rosso Bianco collection before being bought and restored by Alfredo Brener.
The 450S will be the star of a hefty Maserati presence, but the concours is also celebrating of McLaren in 2014 and promising a stellar line-up of racers and road cars.
Another racing anniversary being marked is 25 years since the C9 Sauber-Mercedes' 1989 Le Mans win. Driver Jochen Mass will also be at the event.
Other highlights will include the aluminium-bodied 1930 Duesenberg Model J Speedster with signature 'disappearing top' from the Californian Lyons collection.
There will also be a wealth of concepts from the likes of Packard and Chrysler.
