I think this is a Duesenberg racing a GS4. It's an original oil painting, displayed in the lobby of the Owls Head Transportation Museum, near Rockland, Maine. I wish it was a poster! Sorry about the poor quality of the picture, but I knew the subject would be welcomed here.

Beautiful painting! It could be a "Deusey", but based on the shape of the hoodline and grille, I'm guessing that it is a custom bodied Packard. What do any of you other gearheads out there think?
