Allow me to put in a vote for Bill Reddig as the artist . . . looking through Pat Foster's Nash Styling Sketchbook (where the subject car appears), his artwork appears more than any other when sports cars are the subject and the style is similar. In fact, the drawing Paul posted above is in fact by Reddig, not Flajole according to the book. In any case, the actual subject car appears at least three times in the book and is listed as "artist unknown". Could have been Andersen, Flajole, Reddig, Don Butler, Jack Garnier or even someone else.
The car name, however, is visible and mentioned. It was called "Wisp".
