What actually exists are 1:24 models of the car made by the Franklin Mint, by one account, from drawings found in a barn on the remote Central Pennsylvania estate of Guy de LaRouche.
The legend says that the Duesenberg Coupe Simone was created by the coachbuilding firm Emmet-Armand on the Duesenberg Type J frame in response to a special order from French cosmetics magnate Guy (or Gui) de LaRouche (or LaRoche). The coupe took three years to build and was finished after the bankruptcy of Cord and the end of Duesenberg production. The Coupe Simone was named for LaRouche’s lover and was intended to be a gift to her. It was sent to France for LaRouche’s approval, before it was to be exhibited at the 1939 New York World’s Fair, but disappeared as the result of a love triangle and the outbreak of the Second World War. The Coupe Simone was either destroyed during the war, or remains forgotten today, rusting away, in a barn somewhere in rural France.
An alternative story contends that plans for the car were drawn up in the 1930s, but the car was never built, and only the Franklin Mint models made from drawing re-discovered decades later were ever actually built.
Another version contends that neither car nor drawings nor French cosmetics king ever actually existed, and the model car was invented in the late 1990s by a couple of Franklin Mint designers, who made up a romantic story to explain the Art Deco automobile they had imagined.
