Orange Crush Thermometer (Does anyone have more information on this?)

I really don't know anything about thermometers or advertisement signs. I saw this at a flea market and bought it for $60. I don't have any intention of selling it, but I was just curious how much the value is, if it is authentic (I think it is), and what year/era it was from. I've already tried using Google for information, but the only thing that comes up was ebay ads. Thanks in advance for any helpful information!
