I believe these are a newer fantasy thermometer manufactured probably in the 1990s. There have been many on ebay over the years including some in their original cardboard boxes. There are 7 of them on ebay right now. Prices and condition have been all over the map, from mint in the box to phoney rustic. I wouldn't consider them to be a real vintage collectable. I don't even know if Pepsi had anything to do with their manufacture. Perhaps they just licensed their name to be used on the product. Cheers, Don.
