This is a vintage Coca-Cola Coke Bottle Display Lamp known as “Deep Freeze”. It is made of solid frosted glass or Lucite? as is the base or stand. When powered on it lights up the base of the bottle with 3 different colors. In good condition with a few flaws - there is a fain red mark on the bottle, the lid has a small chip in it, the plug in connector in the base is a little loose so you have to hold it in place with your finger when you push the adapter in. Tested and works great. Please see photos for details and message with any questions.
