I don't know about Roger and Gabby, but I have seen these in car shows, and featured in magazines from the early fifties. It is a big round tube that is mounted to the top of the door and has a vent through the window. It forces air past a wet grill to cool the air. It is sort of like an air conditioner, but isn't really. Swamp cooler is the name given to the unit for a house that functions much the same way only must use a fan to force the air over the condenser. If you visit Pheonix, Arizona you will see lots of them mounted on the roofs of mobile homes and older houses.
