This thermometer was an advertising piece for TRICO Wiper Blades that would hang in a garage or gas station. It is shaped like one half of a windshield wiper swipe and the glass is raised. The metal is in very good shape. It has a bracket on the back to support hanging it on a wall. Great for that man cave or garage. This is probably from the 60's. It measures 15 inches x 9 1/2 inches. It appears to work. It was in the barn when I photographed it and it is a mid 80's kind of day in August and it reads 85 degrees. There is no rust on the metal. The inside of the glass has a little bit of dust that is sticking due to static I believe. Contact us with questions should you have any concerns because we do not accept returns. I have seen plain round advertising thermometers offered for sale for more than what we are asking. This is unique. We must collect 6% Pennsylvania Sales and Use Tax at checkout.
