This is a Vintage Original Coca Cola Thermometer.  It is extremely rare to find an original and vintage thermometer in this condition.  this thermometer is in excellent condition, it is older, but the paint is in excellent shape for the age.  It is made of painted metal. 
 
There are paint flaws and chips - this is a 29.5 inch tall and approximately 9 inch wide thermometer.  It appears to be working correctly judging by the temperature in our facility at the time of photoing.
