Forerunner of Convair 103?

Sorry for this time not posting pictures of an aircraft. It’s a car. With a propeller. And I don’t think it is connected through the fin by any shaft with the engine. SDASM, where the picture is from, calls it “Stout Air Car” (they admit not to be sure). Well, William Bushnell Stout IMHO designed “Sky Cars”, not “Air Cars”. But, the similarity to the Convair 103 aka Stout Sky Car IV aka Spratt-Stout Model 8 Sky Car is stunning. And – the person on the left side in the second picture seems to be William Bushnell Stout!

What do you say?

Thank you for interest + answers!:)
