According to the Sotheby’s info, it couldn’t have been the one in the film. I know the story about the Madame Michelin car, having known and had dealings with Red Dellinger back in the 80s when I first got my 11B. There was an authentic one at Arras in 2009, the man that owned it said he owned the MM car (as I recall) but it wasn’t there.
