Here are comments from the RM Auction listing:

Although the story of Rita Hayworth’s Lincoln Continental continues to be riddled with mystery, the case for the Astor Collection’s car may be quite convincing. Ultimately, one of the best assessments was delivered by Jim and Cheryl Farrell, who wrote, “This may be one of those cases where the folklore passed down from each owner to the next turns out to also be fact. The delivery details, prior photos, location and the car itself all seem to say this really is Rita Hayworth’s ’41 Continental!”
