One of my all time favorites. Of course, in fairness it should be noted that this was not exactly a common sight even back in 1937. In fact the one you posted is a one-off 135 MS Special Roadster that was modified specifically for a '37 car expo.
Here’s another period one-off that always draws a crowd; the 1938 Phantom Corsair:
One of the earliest cars to have shaved door handles with electrically-actuated latches. Also one of the first cars to have a “door ajar” warning. And one of the only cars to have ever come with an altimeter. I suppose that’s apropos because Lycoming built the engine.
Seats 6 in a 4+2 configuration. The back seat is so narrow because the booze cabinets take up the extra room.
