Up for auction is a remarkable Vintage Prestone Anti-Freeze Porcelain Thermometer Sign measuring 9 x 36 inches. This iconic piece of American automobilia features bold and legible graphics, though it displays significant porcelain chipping and rust spots throughout, especially along the edges and around the 50-60 degree Fahrenheit marks. The glass thermometer tube remains intact, with the red fluid clearly visible, adding to its charm. The reverse side bears signs of wear and has been spray-painted black down the center, with a non-original wooden slat affixed for reinforcement. Despite its condition, this collectible sign presents a unique opportunity for enthusiasts and collectors alike, embodying the essence of mid-20th century advertising. Perfect for display, this Prestone sign is sure to make an impression in any collection.
