Just as said, a mini version of an evaporative cooler. Held in place by the window being rolled up to clamp it in place, Put some water in it and as you drove down the road a wind actuated fan in the front blew across a wet screen and sent cool air into the car. Kind of a hassle so we only used one when on longer trips in the heat of summer before A/C was common.
